|---|---|---|---|
| 1 ms | = 0.001 s | ≈ 0.00001666666667 min | ≈ 2.777777778e-7 h |
| 10 ms | = 0.01 s | ≈ 0.0001666666667 min | ≈ 0.000002777777778 h |
| 100 ms | = 0.1 s | ≈ 0.001666666667 min | ≈ 0.00002777777778 h |
| 1000 ms | = 1 s | ≈ 0.01666666667 min | ≈ 0.0002777777778 h |
Where the millisecond fits
The next smaller time unit is the microsecond (µs). 1 ms = 1000 µs, and 1 µs = 0.001 ms.
The next larger time unit is the second (s). 1 ms = 0.001 s, and 1 s = 1000 ms.
