Mathematical Foundation

Time to decimal conversion is based on the relationship between minutes and hours. Since there are 60 minutes in an hour, we divide minutes by 60 to get the decimal portion of an hour. This decimal is then added to the whole hours to get the final decimal hours value.

  • Convert hours to minutes by multiplying by 60
  • Add the minutes to get total minutes
  • Divide total minutes by 60 to get decimal hours
  • Round result to desired precision
  • Common conversions: 15 min = 0.25, 30 min = 0.5, 45 min = 0.75
  • Used in payroll, billing, and scientific calculations
