=HOUR(A2) * 3600 + MINUTE(A2) * 60 + SECOND(A2)Īgain, the formula in B2 of the above spreadsheet returns the value 9030. The same result can be obtained using the Excel Hour, Minute and Second functions, as shown below: (The reason that this method works is because Excel times are internally stored as decimal values, with the value 1.0 used to represent 24 hours, and therefore, the value 1/86400 used to represent 1 second). 2 hours 30 minutes and 30 seconds is equal to 9030 seconds. The easiest way to convert a time to a number of seconds is to simply multiply the time by 86400, which is equal to 24*60*60 (the number of seconds in one day):įor the time 02:30:30, the formula in B2 of the above spreadsheet returns the value 9030. The spreadsheets below show the formulas that can be used to convert a time to a number of seconds in Excel. =HOUR(A2) * 60 + MINUTE(A2) + SECOND(A2) / 60Īgain, the formula in cell B2 of the above spreadsheet returns the value 150.5. The same result can also be obtained using the Excel Hour, Minute and Second functions, as shown in the spreadsheet below: (The reason that this method works is because Excel times are internally stored as decimal values, with the value 1.0 used to represent 24 hours, and therefore, the value 1/1440 used to represent 1 minute). 2 hours 30 minutes and 30 seconds is equal to 150.5 minutes. The simplest way to convert a time to a number of minutes is to multiply the time by 1440, which is equal to 24*60 (the number of minutes in one day):įor the time 02:30:30, the formula in cell B2 of the above spreadsheet returns the value 150.5. =HOUR(A2) + MINUTE(A2) / 60 + SECOND(A2) / 3600Īgain, the formula in cell B2 of the above spreadsheet returns the value 2.5.Ĭell B2 of the spreadsheets below show the two formulas that can be used to convert a time to a number of minutes in Excel. Although this formula is much longer than the simple multiplication shown above, some people prefer it. The second formula that can be used to provide the same result uses the Excel Hour, Minute, and Second functions. (The reason that this method works is because Excel times are internally stored as decimal values, with the value 1.0 used to represent 24 hours, and therefore, the value 1/24 used to represent 1 hour). Example Convert 1 degrees30 minutes and 30 seconds angle to decimal degrees: 1º 30 30' The decimal degrees dd is equal to: dd d + m/60 + s/3600 dd 1º + 30/60 + 30'/3600 1. 2 hours 30 minutes and 0 seconds is equal to 2.5 hours. For angle with d integer degrees m minutes and s seconds: dº m s' The decimal degrees dd is equal to: dd d + m/60 + s/3600. In this case, the time is simply multiplied by 24 (the number of hours in one day). The simplest formula to convert a time to a number of hours is shown below. If your latitude is South or West, the decimal is negative.The following spreadsheets show two different formulas that can be used to convert a time to a number of hours in Excel. If the latitude or longitude is North or East, the decimal is positive. Determine if the answer is positive or negative.Add this decimal to your previous answers and get 119.50555 degrees. In the example, the latitude has 20 seconds. Putting this all together into a string gives 1 d 21 h 05 m. Rounding to 0 decimal places results in a value of 5 minutes. Divide the number of minutes in the latitude or longitude by 3,600. That leaves the minutes which are worked out by subtracting hrs from hrs to leave just the decimal. In the example, the latitude has 30 minutes. Therefore, divide the number of minutes in the latitude or longitude by 60. In decimal notion, the example should be written as 119.00 degrees. Place the degrees before the decimal point.Find the degree of the latitude or longitudeĪs an example, in the latitude 119 degrees 30 minutes 20 seconds, more commonly written as 119° 30′ 20”, the degree is 119.
