About Time Units
Time is measured in seconds (s), with sub-second prefixes and the familiar minutes, hours, and days for longer spans.
Embedded timing crosses many scales: nanoseconds for logic propagation, microseconds and milliseconds for task durations, and seconds through days for duty cycles and battery life. Telemetry timing and execution durations are usually logged in milliseconds.
Example conversions
- 1 ms = 1000 µs — a typical sensor read.
- 1 h = 3600 s — a duty-cycle window.
Frequently asked questions
How do I convert milliseconds to seconds?
Divide by 1000. 1500 ms is 1.5 s.
How do I convert hours to seconds?
Multiply by 3600. 2 h is 7200 s.
How do I convert microseconds to milliseconds?
Divide by 1000. 500 µs is 0.5 ms.
