To convert femtoseconds to microseconds, multiply the value by 1 × 10⁻⁹. To go the other way, multiply microseconds by 1,000,000,000 to get femtoseconds.
| Femtoseconds (fs) | Microseconds (µs) |
|---|---|
| 1 fs | 1 × 10⁻⁹ µs |
| 5 fs | 5 × 10⁻⁹ µs |
| 10 fs | 1 × 10⁻⁸ µs |
| 25 fs | 2.5 × 10⁻⁸ µs |
| 50 fs | 5 × 10⁻⁸ µs |
| 100 fs | 1 × 10⁻⁷ µs |
| 250 fs | 2.5 × 10⁻⁷ µs |
| 500 fs | 5 × 10⁻⁷ µs |
| 1,000 fs | 1 × 10⁻⁶ µs |
| 2,500 fs | 2.5 × 10⁻⁶ µs |
| 5,000 fs | 5 × 10⁻⁶ µs |
| 10,000 fs | 1 × 10⁻⁵ µs |
| 100,000 fs | 0.0001 µs |
| 1,000,000 fs | 0.001 µs |
Femtosecond (fs). A femtosecond is 10⁻¹⁵ of a second, the scale of laser pulses and chemical reactions.
Microsecond (µs). A microsecond is one millionth of a second.
There are 1 × 10⁻⁹ microseconds in one femtosecond.
Multiply the number of femtoseconds by 1 × 10⁻⁹. For example, 10 femtoseconds equal 1 × 10⁻⁸ microseconds.
One microsecond equals 1,000,000,000 femtoseconds.
1 × 10⁻⁶ microseconds. Other common values: 100 femtoseconds = 1 × 10⁻⁷ microseconds and 10,000 femtoseconds = 1 × 10⁻⁵ microseconds.
