Microsecond quick reference
| Microsecond | Minute | Hour | Nanosecond |
|---|---|---|---|
| 1 µs | ≈ 1.666666667e-8 min | ≈ 2.777777778e-10 h | = 1000 ns |
| 10 µs | ≈ 1.666666667e-7 min | ≈ 2.777777778e-9 h | = 10000 ns |
| 100 µs | ≈ 0.000001666666667 min | ≈ 2.777777778e-8 h | = 100000 ns |
| 1000 µs | ≈ 0.00001666666667 min | ≈ 2.777777778e-7 h | = 1000000 ns |
Where the microsecond fits
The next smaller time unit is the nanosecond (ns). 1 µs = 1000 ns, and 1 ns = 0.001 µs.
The next larger time unit is the millisecond (ms). 1 µs = 0.001 ms, and 1 ms = 1000 µs.
