To convert microseconds to nanoseconds, multiply by 1000.
The calculation uses 1 µs = 1000 ns. Results are displayed to at most 10 significant digits. Definitions can be exact while a displayed decimal is rounded. Match the displayed precision to your original measurement.
The formula
value in ns = value in µs × 1000
µs- Input unit: microseconds
ns- Output unit: nanoseconds
How to use this calculator
- Enter a value in µs.
- Multiply by the stored conversion factor.
- Read the result in ns; divide by the same factor to convert back.
Worked examples
Worked conversion
1 µs × 1000 ≈ 1000 ns.
Reverse conversion
1000 ns ÷ 1000 ≈ 1 µs. Rounding intermediate values can change the last displayed digit.
Frequently asked questions
What factor does this converter use?
It uses 1000 ns per µs.
Why can another converter show a slightly different answer?
Check the unit convention first (such as US versus Imperial or decimal versus binary), then compare rounding. Measurement uncertainty is separate from the unit conversion.
