Time-unit conversion involves interpreting equivalent durations across seconds, minutes, hours, days, and weeks using fixed relationships: 60 seconds per minute, 60 minutes per hour, 24 hours per day, and 7 days per week. Quantities may be represented as whole numbers, fractions, decimals, or mixed units, with the numerical value changing inversely with the size of the unit; calendar-specific variations, such as leap years, and more generalized dimensional-analysis treatments are outside this scope.
To convert units of time, use the relationship between the units:
When changing to a smaller unit, multiply. When changing to a larger unit, divide.
Example: Convert hours to minutes.
Since minutes are smaller than hours, multiply by :
The hours cancel, leaving minutes:
