⚡ Microseconds to Seconds: the quick answer

1 µs = 1 × 10⁻⁶ s 1 microsecond equals 1 × 10⁻⁶ seconds

To convert microseconds to seconds, multiply the value by 1 × 10⁻⁶. To go the other way, multiply seconds by 1,000,000 to get microseconds.

↔ Convert seconds to microseconds instead

🧮 Formula

Microseconds to Seconds
s = µs × 1 × 10⁻⁶
Seconds to Microseconds
µs = s × 1,000,000

Where

  • µs = the time in microseconds
  • s = the time in seconds
Every unit here is defined by its time in seconds, so the conversion factor is (seconds per microsecond) ÷ (seconds per second).
