About the microseconds converter
One microsecond (μs) is one-millionth of a second. Despite being tiny, it’s crucial for precise timing in computing, trading systems, scientific experiments, and real-time applications.
Why it matters
Measuring at the microsecond scale enables accurate profiling, better scheduling, and reliable synchronization across distributed systems and high-performance code paths.
Typical conversions
- μs → Date: derive a human-readable timestamp from a microsecond value
- μs → ms / s / min / h / d: express very short or long intervals in friendlier units
- μs → months: coarse monthly estimate (≈ 30.44 days per month)
Code snippets
Convert microseconds to other units:
JavaScript
const us = 1500000;
const ms = us / 1000;
console.log(`${ms} ms`);Python
us = 1500000
ms = us / 1000
print(f"{ms} ms")PHP
$us = 1500000;
$ms = $us / 1000;
echo $ms . " ms";Common errors
| Issue | Explanation |
|---|---|
| Assuming microseconds in JS Date | JavaScript Date objects operate in milliseconds, so microseconds must be divided by 1,000. |
| Precision loss | Floating-point types may lose precision for large microsecond values; use integers where possible. |
FAQ
- How many microseconds are in a millisecond?
- There are 1,000 microseconds in one millisecond.
- How do I convert microseconds to seconds?
- Divide the microseconds by 1,000,000 to get seconds.
- Does JavaScript support microsecond precision?
- No, JavaScript timers work with milliseconds; use performance APIs for higher precision.
- Why use BigInt for microseconds?
- BigInt stores very large integers without losing precision.
- What is the symbol for microsecond?
- The symbol is μs.
