Transcription of Adding Time on a Calculator
1 Adding time on a Calculator Adding time on a Calculator without converting the minutes to hundredths is inaccurate. Units of time are calculated as 60 minutes equals 1 hour, but a Calculator uses units of 100. For example, if an employee worked 9 hours and 30 minutes on one day and 8 hours and 45 minutes on the day, the time card would display 9:30 for day 1 and 8:45 for day 2. If you were to add these without converting on a Calculator , you would get hours which is 17 hours and 45 minutes. = 17 hours and 45 minutes. This is inaccurate. When you change the minutes to 100ths using the conversion chart below, the 9:30 becomes and the 8:45 becomes If you add these two numbers on the Calculator you get , which is 18 hours and 15 minutes. = 18 hours and 15 minutes. This is correct. A time conversion chart is provided here to help with the converting of the time from minutes to 100ths prior to Adding it on a Calculator .
