Hours to Minutes Converter

Hours to Minutes

Convert hours (hr) to minutes (min). Both measure duration, and the conversion comes up in scheduling, project management, cooking work.

The Formula

`` minutes = hours × 60 hours = minutes × 0.0166666666667 `

One hour is 60 minutes, and one minute is 0.016667 hours.

What Each Unit Is

Hours (hr) — 3,600 seconds. Egyptian division of day and night into twelve parts each, later equalised.

Minutes (min) — 60 seconds. From Babylonian base-60 arithmetic, inherited through Greek astronomy.

A Sense of Scale

• A working day is 8 hours
• A transatlantic flight is 7–8 hours
• A pop song is 3–4 minutes
• A meeting slot is 30 minutes

Precision

The factor 60 is exact by international agreement, not a rounded approximation. Any imprecision in a result comes from your input, not the conversion.

In Code

`javascript const hourToMinute = (value) => value * 60; ``

How Many Decimals Do You Need?

Rounding the factor costs accuracy, and how much depends on the factor. Converting 137 hr with the factor truncated at each decimal place:

Decimals kept	Factor	137 hr becomes	Error
0	60	8,220	—
1	60	8,220	—
2	60	8,220	—
3	60	8,220	—
4	60	8,220	—

A rule that holds for any conversion: round once, at the end. Rounding the factor and then multiplying compounds the error through every subsequent calculation, while carrying full precision and rounding the final answer does not.

The right number of significant figures is set by your input, not by the converter. If you measured hours to three significant figures, the answer in minutes is only good to three — writing more digits claims precision the measurement never had.

Other Conversions From Hours

The same value in every other unit this converter supports for time:

From	To	Unit
1 hr	3,600 s	Seconds
1 hr	3,600,000 ms	Milliseconds
1 hr	0.0416667 d	Days
1 hr	0.00595238 wk	Weeks
1 hr	0.00138889 mo	Months
1 hr	1.1416e-4 yr	Years

Chaining conversions works — hours to metres to feet gives the same answer as hours to feet — but each step rounds, so a chain of three conversions carries three roundings. Convert directly where a direct factor exists.
