How to Convert Hours to Minutes (h to min)
Time conversions help with project planning, payroll hours and working out how long a loan or COE period really is. This guide shows how to convert hours into minutes by hand, with examples and a quick-reference table.
The conversion
To convert hours to minutes, multiply the value by 60. To go the other way, divide by the same number (or multiply by 0.0166666667). For a quick estimate, multiply by about 60.
Minutes = hours × 60
Worked examples

Mistakes to avoid
Mixing similar-sounding units
US and imperial gallons, pints and tons are different sizes, and decimal kilobytes differ from binary kibibytes.
Forgetting squared and cubed units
Area and volume factors are the length factor squared or cubed, so 1 m² is about 10.76 sq ft, not 3.28.
Dropping the units
A bare number without a unit is easy to misread later. Always write the unit with the result.
Background
For everyday use, three or four significant figures are usually enough. Engineering, science and trade documents may need more, and rounding should happen only at the end of a calculation.
Many conversion factors are exact by definition. The inch has been defined as exactly 2.54 centimetres since 1959, and the pound as exactly 0.45359237 kilograms, so conversions involving them can be as precise as you need.
Singapore adopted the metric system in the 1970s, replacing imperial units and traditional Chinese measures in most official uses. Metric units are now standard in schools, trade and government, but older units survive in property, markets and imported goods.
