Hours Conversion Into "day Shift" & "night Shift"

I am trying to figure out how to write a formula to figure out production cycle time.
We will be building 8 "widgets" a day.
We will work 10 hours a day.
There is a 20 minute break at 9:20 am.
Production shuts down for lunch 30 minutes for lunch at 12:30.
Production starts at 6:00 am.
Here is what I can do.
Production cycle time = (10*60)-30/8 or 71.25 minutes
If we start at 6:00 am, the first scheduled cycle completion time = TIME(6,0,0+71.25/1440)

My problem is when I am trying to use a logical "IF' statement to account for the 20 minute break or lunch and still calculate the end of each cycle time through the day I receive a number of error messages.
This is the formula I am trying to make work. I have the cell the formula is in, formatted with a "mm,ss" format.
=(IF(D4+G1/1440>9:20,(D4+G1)/24,(D4+G1+15)/1440))
I have included an attachment to help (a picture is worth a thousand words).

Any help will be greatly appreciated.
I have bought a number of books in an attempt to figure this out, and I am still stumped

Good afternoon!

I'm working with Excel 2003 sp 3 on Windows xp.

I have been banging my head trying to jar loose the formula to calculate man days where 1 equals 8 hours. I have one that was given to me by a coworker:

=INT(Q3/8)+(((Q3/8)-(INT(Q3/8)))*0.8)

That calculates man days from total hours. I need a formula that will total man days and return the man day answer. Example:

weekending 12/25 = 16.2 which is 16 man days and 2 hours
weekending 1/1 = 24.7 which is 24 man days and 7 hours

Total = 41 man days and 1 hour

I have also been asked if there was a way for a number to be entered into a spreadsheet and automatically put in order without a macro or "pushing a button".

Any advice is greatly appreciated!

Happy New Year!

I often use if statements to return empty cells, for example:

=IF(a1=0,"ERROR","")

The trailing "" returns an empty cell. The problem is, it is not TRULY empty. If I fill that formula down, I cannot, for example, jump from one "ERROR" cell to the next by hitting Ctrl arrow-down because it seems to think that these empty cells have contents.

Is there a way to designate, in such a formula as above, to return a TRULY empty cell?

Thanks

Hi, hope someone can assist, i want to add some arrow syimbols in to a formula, so that when the formula works out it shows an up arrow for higher or a down arrow for lower, i am using this formula at the moment because i dont know any better but it works, putting in the word up or down:

I have entered the following formula in to a cell: =IF(S3<R3,"DOWN","UP") it works however i want to replace the word Down and up with the relevant arrows symbol. How do i do this?

Thanks

I have a co-worker's file that he is having trouble with. He is using Excel 2000 SP3. When copying a cell with a formula in it of "=D6+C6" and pasting it into the next cell down, it will display the same value in the cell as the calculated value from above, but has the correct formula displayed in the formula bar of "=D7+C7".

Example:
A1: 50
A2: 10
B1: 60
B2: 20

A3: Formula: =A1+A2 Displays: 60
Right click A3, Copy, right click B3, paste
A3 displays 60

When I click save, it will change the display value to 80.

I am trying this on his workstation and mine. Mine has Office 2010, so I think there might be an issue with the file itself.

Also, not just copy and paste. I can also just click the top cell after filling in the formula and then drag the bottom right of the cell downward and it will do the same of filling in the correct formula, but have the incorrect value.

I know that I could get him to just click save each time before really looking at the results, but that is just a band aid to the problem.

Any ideas how to fix this?

I have cells in a column, some colored yellow, some not. I am trying to use
the SUMIF function to sum only the cells in the range that are colored. Can
this be done? Can I enter something in the "criteria" part of the formula
that can do this?

=SUMIF(D3:D13,"criteria",D3:D13)

I also tried to use the CELL function's color feature, but I couldn't get it
to work right. I don't know how to get Excel to recognize if a cell is
colored in a formula.
=CELL("color",cell)

It might just be that I don't know what this means in Help:

"color" --> 1 if the cell is formatted in color for negative values;
otherwise returns 0 (zero).

Can anyone help?

I need help desparately. Last night I spent several hours working on an
Excel 2002 spreadsheet and it has disappeared.

I saved it routinely as I was making many changes updates etc. I opened
original file --stuff.xls --- made changes and saved it as again as
stuff.xls. I have done this several times before.

Today, when I go to open stuff.xls, it is nowhere to be found!!!!! I have
done a search, for any file modified since Thurs and nothing has appeared. I
have checked the recycle bin, this did not go into auto recover nothing of
the like. I am just traumatized, because I have NEVER had anything like this
happen before.

I even thought perhaps I didn't save it as often as I thought, (I know that
I did) but I remembered that I saved it at least once and I can't even find
an Excel file that has been modified since Thurs!!!

Does anyone have any idea what could have happened to this file?? BTW, I
have prayed, rebooted, run spybot, called witch doctor, all with no success.

I have never had a file to just disappear with no trace. Any help would be
greatly appreciated.

Thanks in advance---

Hello,

I am new to using Excel and I am not very computer literate. I am looking for some help with a spreadsheet I am making. Here is the problem:

I have a column of 14 numbers in cells A1 to A14. If all of these values are less than 2%, I would like a "Pass" to display in cell B1. If any of these values are greater than 2% I would like a "Fail" to display in cell B1.

I have got a formula that works for a single cell but I can't figure out how to get it to apply to more than one cell. For example, I have entered =IF(A1<2,"Pass","Fail") in cell B1. Now if the value I enter in A1 is less than 2, it shows a "Pass", and if the value in A1 is greater than 2 it shows a "Fail" in cell B1. How can I get this to apply to all of the cells from A1 to A14?

If somebody could help me out that would be great.

Thanks,
Randy

Hi,

Im working with a large data spreadsheet that has Yes and No answers in different columns. There are blanks within the selection too.
I need to calculate only the Yes.
I have tried using the filters in the Pivot Table field list and they are not working.
So now i'm trying to add a COUNTIF formula in the Calculated Fields section.
The formula I'm using is =Countif('Time limit extension'="yes") and i get the answer "too few."
What should I be using in the formula to get the calculated field to work? I have search the whole forum and I haven't found an answer that can help me.

Please HELP!!!

is it possible to put two formulasinto one cell?

On the attached timesheet there are columns IN, OUT, IN,OUT
The lunch time is worked out by deducting 'C8 from C9' and this works fine when all 'IN, OUT' cells are filled in but for some reason when just the first two cells are filled in it gives a -12 hour answer.

looking at cell 'C11 ' in the attached worksheet, I currently have the formula
=IF(C13=0,","SUM(C9-C8)) The reason for this is to make it look tidy by having blank cells until a calculation is needed,, My problem is, If someone just comes in for the morning one day for instance 8am to 12 noon then they won't have lunch, but C11 will show -12:00
Can I put another formula into C11 to tell it not to deduct C8 from C9 until a time is put into C9.
The following is the sort of thing (many variations) I have been trying but because I'm hopeless at formulas I'm not having any success
Thanks

=IF(C13=0,","SUM(C9-C8))OR,IF(C9,ISBLANK,"",SUM(C9-C8)

Hi,
I made a simple worksheet that we have been manually entering the time for employees, but there are too many errors (even with simple math). Can someone help me convert the time of ex: written 8-4:30 or 10-3 (meaning 8:00am to 4:30pm) where you have the total weekly hours? Right now I have a column for overtime. Is there a way to automatically calculate the over time also? The work day is 8-4:30 with a half hour lunch (lunch is not calculated into the hours, so you minus a half hour). 8-4:30 equals 8 hours. So, if a person works 8am to 6:30pm, how can I set it up where in the first row of time, I will type in 8-6:30pm. In the totals column to the far right, it will display 8 hours. In the (O.T.) column, it will display 2 hours.

This way, when I call in my payroll, I will have the total "regular" hours in one row and underneath, I will have the total overtime hours.

Or... does anyone have a better solution to keeping track of their hours?

Thanks!
Marty

How do I set the formula if

if F1...I1 <10 = Pass, >=10 Fail (and highlighted red), and any cell between F1....I1 is empty = blank

Hi Everyone,
I have searched online and in help but can't seem to find the best solution...

I have values like 00904BB303D6 that need to become: 00:90:4B:B3:03:D6 (the value is always 12 digits, and the : needs to appear every two digits.) Is there a formula that can easily do this for me? Your suggestions are greatly appreciated!

Thanks in advance!!!!

I am trying to write a formula that uses both an if statement and a vlookup statement.

It's for a house cleaning price list, with two sets of prices. I want the formula to say if the value in E7 is R, i want to lookup the value for the house in the second column. If the value in the cell is anything else, i want to lookup the value for the house in the third column.

So in sense, my formula should look like =IF (E7=1,"=VLOOKUP(A10,'Clean Prices'!$A$2:$C$58,2,FALSE)","=VLOOKUP(A10,'Clean Prices'!$A$2:$C$58,3,FALSE)")

But it doesn't work. Is it possible to nest a vlookup in an if statement?

I'm looking for a formula that pulls the text from a cell unti it hits a space.

I'm using the formula below but keep getting #VALUE results


B1: =LEFT(A1,FIND(",",A1,1))


I know it's not that hard but can't figure it out.

thanks for the help
