Unit Conversions (Time)
Time does not follow powers of 10. Learn the key facts: 60 seconds in a minute, 60 minutes in an hour, 24 hours in a day.
Unlike the metric system, time uses different conversion factors:
The same rule applies: to go from a larger unit to a smaller unit, multiply. To go from a smaller unit to a larger unit, divide.
Be careful with remainders. For example, 130 minutes is not 2.1667 hours in everyday language; it is 2 hours and 10 minutes.
The slider converts hours to minutes. Try entering different values.
