421 mu = 0.421 ms. To convert microseconds to milliseconds, divide by 1,000: 421 ÷ 1,000 = 0.421.
How to convert microseconds to milliseconds
ms = mu × 0.001
- 1 mu = 0.001 ms (and 1 ms = 1,000 mu).
- Multiply the amount by the factor: 421 × 0.001 = 0.421.
- Answer: 421 mu = 0.421 ms.
Shortcut: dividing by 1,000 gives the same result as multiplying by 0.001.
