Time converter
Months and years use average Gregorian lengths (30.436 875 and 365.2425 days); calendar months and leap years vary.
1 hour = 60 minutes
How it’s calculated
min = h × 60
- Multiply the value in hours by 60.
- To go back, divide by 60 (or multiply by 0.01666666667).
- 1 h = 60 min · 1 min = 0.01666666667 h

Find the conversion factor
By definition 1 h = 3600 s and 1 min = 60 s, so 1 h = 60 min. Source: BIPM SI Brochure (9th ed.) (SI prefixes and accepted units).
Multiply by the factor written as a fraction
Put h in the denominator so it cancels, leaving min.
Calculate (unrounded)
Round the answer
Rounded to 5 significant figures.
Answer: 60 min
1 h in other units
Batch convert h → min
- 1 h = 60 min
- 5 h = 300 min
- 10 h = 600 min
- 25 h = 1500 min

Frequently asked questions
Which time units can I convert?
seconds (s), milliseconds (ms), microseconds (µs), nanoseconds (ns), minutes (min), hours (h), days (d), weeks (wk), months (mo), years (yr).
How accurate are the results?
Every unit is stored with its exact defining factor (NIST SP 811, NIST Handbook 44 or the BIPM SI Brochure). Calculations use double-precision arithmetic and are rounded only for display, to 5 significant figures by default (trailing zeros dropped, so 1 km shows as 1000 m). You can choose Auto (up to 10 digits), fixed decimals or more significant figures, or switch to scientific or engineering notation.
