Converting Milliseconds to Microseconds
Real-time systems and embedded programming often require microsecond precision. Converting from milliseconds ensures accurate timer configurations.
Whether you are setting a hardware timer register or tuning a control loop, this tool turns ms values into the µs scale your firmware expects.
Common Use Cases

The Formula
Examples
| Milliseconds | Value | Microseconds |
|---|---|---|
| 2.5 ms | 2.5 × 1,000 | 2,500 µs |
| 0.1 ms | 0.1 × 1,000 | 100 µs |
| 16.67 ms | 16.67 × 1,000 | 16,670 µs |

Frequently Asked Questions
How many microseconds in 1 millisecond?
1 millisecond equals exactly 1,000 microseconds.
What is 0.5 milliseconds in microseconds?
0.5 ms equals 500 microseconds.
Why do embedded systems use microseconds?
Hardware timers and real-time operations need precision that milliseconds cannot provide. A 1 ms error can cause motor jitter or communication failures.
What is the Arduino delayMicroseconds limit?
Arduino's delayMicroseconds() is accurate for values up to about 16,383 µs. For longer delays, use delay() with milliseconds.
What is 16.67 ms in microseconds?
16.67 ms ≈ 16,670 µs — the frame time for 60 fps video.
