Hours to microseconds converter
Microseconds (µs)
1 hour = 3,600,000,000 microseconds
How to convert hours to microseconds
µs = h × 3600000000
Multiply the number of hours by 3600000000 to get microseconds. Going the other way, divide by 3600000000 (or multiply by 2.77777777778 × 10^-10).
One hour is exactly defined as 3600000000 microseconds (to 12 significant figures), and one microsecond is 2.77777777778 × 10^-10 hours.
Worked examples
- Convert 5 hours: 5 × 3600000000 = 18,000,000,000 18,000,000,000 microseconds.
