⚡ Seconds to Microseconds: the quick answer

1 s = 1,000,000 µs 1 second equals 1,000,000 microseconds

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

↔ Convert microseconds to seconds instead

🧮 Formula

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

Where

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