Time Unit Conversion:
1 Second (s) = 1,000,000 Microseconds (μs) | 1 Microsecond (μs) = 1×10⁻⁶ Seconds (s)
s = μs × 1e-6 | μs = s × 1e6 (Results shown with 6 decimal places)
Microsecond (10⁻⁶ s) — used for fast events: computer operations, sensor response, light pulses

| Unit | Symbol | Factor (vs Second) | Common Uses |
|---|---|---|---|
| Second | s | 1 (base unit) | Everyday time measurement, sports timing, music beats, scientific experiments |
| Microsecond | μs | 10⁻⁶ s (0.000001 s) | Computer processing, sensor response time, light pulses, high-speed photography |
| Microseconds (μs) | ≈ | Seconds (s) | Real-World Example |
|---|---|---|---|
| 1 μs | ≈ | 0.000001 s | Light travels ~300 meters |
| 100 μs | ≈ | 0.000100 s | Fast sensor response time |
| 1,000 μs | ≈ | 0.001000 s | 1 millisecond (camera shutter speed) |
| 100,000 μs | ≈ | 0.100000 s | Human reaction time (fast) |
| 500,000 μs | ≈ | 0.500000 s | Blink of an eye (approx) |
| 1,000,000 μs | ≈ | 1.000000 s | Heartbeat (average adult) |
About microseconds, seconds, and time unit conversions
The relationship comes from metric system prefix rules for time units:
1 s = 1,000 ms = 1,000,000 μs = 1,000,000,000 ns
1 μs = 0.001 ms = 0.000001 s = 1,000 ns
Conversion rule: Multiply by 1e-6 for μs→s; multiply by 1e6 for s→μs
Microseconds are critical for measuring extremely fast events where seconds or milliseconds are too coarse:
For everyday use (cooking, meetings), seconds or minutes are sufficient. Microseconds are for precision engineering and science.
The metric time hierarchy uses consistent base-10 scaling between units:
1 second (s) = 1,000 milliseconds (ms)
1 millisecond (ms) = 1,000 microseconds (μs)
1 microsecond (μs) = 1,000 nanoseconds (ns)
1 second (s) = 1,000,000 μs = 1,000,000,000 ns
Practical examples of this scale:
This converter focuses on μs↔s, but the same decimal logic applies when converting to milliseconds (×0.001) or nanoseconds (×1000).
