What Excel formula should I use to calculate the network uptime by percentage (ie 99.999%)?
One problem is that the number of days in each month varies. So the Uptime percentage will very slightly from month-to-month even with the actual down time being the same. Here's a formula that will calculate the number of days in the month and then calculate the uptime percentage based on that. Assume that column A has your dates and column B has your down time minutes for a given month. The numbers in column B are assumed to be just numbers and not formatted as Time. =(1-SUM(B:B)/(DAY(DATE(YEAR(A1), MONTH(A1)+1,1)-1)*1440))*100 The formula uses the month and year from the date in A1 to calculate the number of days in that month. It doesn't matter what the Day is in that date. FYI: When Excel sees the "Day" function in a formula, it could try to autoformat the cell as a "Date". If it does, you will have to change the cell format back to a Number or a Percentage. If you do format the result as a percentage, remove the *100 from the end of the formula.
What are the formulas in excel for calculating the number of days Ive been alive?
In cell A1 put your Date & Time of birth in the format dd/mmm/yyyy hh:mm Suppose you were born at 17:48 on 20th October 1975 then type in 20/Oct/1975 17:48 (note there is a space between 1975 and 17) In bell B1 type '=Now() In Cell C1 Type '=B1-A1' Thats the number of days you have been alive.

What's the Excel formula to calculate hours and minutes multiplied by income per hour?
Have the time in one cell, and the rate in another.Make sure time in the first cell is formated as HH:MM (hours : Minutes)in a third cell multiply time per ”rate” and the also multiply per “24”. Looks like this;1:30 x $50 x 24 = $75 (or like this, =A1*B1*24)
How do you write the formula to calculate pace per mile (running) in Excel?
Pace per mile is found by taking the overall time divided by the number of miles. So the formula you need to use is: =E2/D2 As far as the formatting goes, the default setting for times in Excel is hh:mm:ss (hours:minutes:seconds). So if you were to simply enter 45:29 into a cell, Excel will show 45:29:00, which actually means 45 HOURS, 29 MINUTES, and 00 SECONDS. You should enter your time of 45 mintutes and 29 seconds as 0:45:29 and you should have no problems. Your formula will give you an answer of 0:10:37 which means 0 hours, 10 minutes, 37 seconds per mile. If the zero in the hour column bugs you, you can change the format of the cell to mm:ss (minutes:seconds) after entering the time in as 0:45:29, and excel will drop the first zero from its display.
Excel 2007 Time Card Calculator?
Hello, I need your help with the following. I need a formula to calculate time card times in Excel 2007. The time need to be rounded up or down to the nearest 15 minutes. Like: 53 --> 00 <-- 7 8 --> 15 <-- 22 23 --> 30 <-- 36 37 --> 45 <-- 52. In other words, if an employee worked 3:52 hours, it will be rounded down to 3:45 and the result will be posted into ADP as decimals like 3.75 hours. The time cards come in the following formar: 2:00PM to 5:23PM 9:05AM to 3:06PM 6:18PM to 11:53PM I need to calculate all these time one by one into decimals. For example 2:00PM to 5:23PM = 3.50 Please help.
How do you write the formula to calculate pace per mile (running) in Excel?
its is the simple divide formula that you expected and you do have to format your cells properly. D2 should just be the number 4 E2 should be this 0:45:29 then in F2 use the formula =E2/D2 and you should get then answer 0:11:22 you can format the cells to not show the hours if you are never going to need them. edit- hmmm??? i get 11:22 just like the website did you try what i suggested? maybe if you open up a new blank sheet and try it. excel already converts time to a decimal for you. 24 hours = 1 day so 24:00:00 = the whole number 1 as a decimal the 1 hour = .041667 so 1/24= 1 hour also reads 1 part of the 24 parts of a day = .041667 also 11:32 * 4 would be 46:08
