Questions people ask
How do I convert hours to minutes?
Multiply by 60. For example 10 h = 600 min.
What is the base unit for time?
The converter uses the second as its internal base. Every unit is converted to seconds and then to the target unit, so any pair of units works.
Where do the conversion factors come from?
From the legal definitions published in NIST Special Publication 811 and the SI Brochure (BIPM). Where a unit is defined exactly, the factor is exact.
