1 second =
1,000,000 microseconds
1 microsecond =
1 × 10⁻⁶ seconds
Formula
µs = s × 1,000,000
Handy values
5 s = 5,000,000 µs · 10 s = 10,000,000 µs · 100 s = 100,000,000 µs

⚡ 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
Every unit here is defined by its time in seconds, so the conversion factor is (seconds per second) ÷ (seconds per microsecond).
