How to Convert Hours to Minutes
To convert hours to minutes, multiply the time by the following conversion ratio: 60 minutes/hour.
Since one hour is equal to 60 minutes, you can use this simple formula to convert:
The time in minutes is equal to the time in hours multiplied by 60.
For example, here's how to convert 3.5 hours to minutes using the formula above.
How Many Minutes Are in an Hour?
There are 60 minutes in an hour, which is why we use this value in the formula above.
Our hour to minute calculator automatically converts your time measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.
Hours and minutes are both units used to measure time. Keep reading to learn more about each unit.
What Is an Hour?
An hour is a unit of time equal to 3,600 seconds (s), the base unit for time. Equal to 60 minutes or 3,600 seconds. [1]
The hour is classified as a standard unit of time. Hours can be abbreviated as hr; for example, 1 hour can be written as 1 hr.
When working with hours (hr) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.
In practice, hours (hr) are widely used across large-scale industrial, bulk, and macro-level time specifications within international standard workflows, engineering documentation, and technical data sheets.
What Is a Minute?
A minute is a unit of time equal to 60 seconds (s), the base unit for time. Equal to 60 seconds. [2]
The minute is classified as a standard unit of time. Minutes can be abbreviated as min; for example, 1 minute can be written as 1 min.
When working with minutes (min) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.
In practice, minutes (min) are widely used across standard time applications within international standard workflows, engineering documentation, and technical data sheets.
When converting time between hours (hr) and minutes (min), keep full floating-point precision (1 hr = 60 min; 1 min = 0.0166667 hr) during intermediate calculations and round only the final minute figure to match your instrument tolerance.
