Time Unit Conversion Tool
Whether you're a programmer debugging code, a scientist recording experimental data, a project manager scheduling timelines, or a student solving physics homework, converting between time units is a frequent and essential task. However, the range spans from extremely short nanoseconds (ns) to vast durations like years, with complex and error-prone conversion relationships.
To address this, we introduce an all-in-one Time Unit Converter that supports instant, high-precision conversion among the following 10 commonly used time units:
- Nanosecond (ns)
- Microsecond (mu) — equivalent to μs (1 mu = 1 microsecond)
- Millisecond (ms)
- Second (s)
- Minute (min)
- Hour (h)
- Day (d)
- Week (week)
- Month (month)
- Year (year)
Simply enter a value, select the source and target units, and get an accurate result in seconds!
🔁 Core Time Unit Conversion Formulas
💡 Note: For simplicity, this tool uses average values for “month” and “year”:
- 1 year = 365.25 days (accounts for leap years)
- 1 month = 365.25 ÷ 12 ≈ 30.4375 days
Step-by-Step Conversion Chain
| Conversion | Formula |
|---|---|
| ns → mu | mu = ns ÷ 1,000 |
| mu → ms | ms = mu ÷ 1,000 |
| ms → s | s = ms ÷ 1,000 |
| s → min | min = s ÷ 60 |
| min → h | h = min ÷ 60 |
| h → d | d = h ÷ 24 |
| d → week | week = d ÷ 7 |
| d → month | month = d ÷ 30.4375 |
| d → year | year = d ÷ 365.25 |
Base Reference: All Units in Seconds
| Unit | Equivalent in Seconds (s) |
|---|---|
| 1 ns | 1e-9 s |
| 1 mu (μs) | 1e-6 s |
| 1 ms | 0.001 s |
| 1 s | 1 s |
| 1 min | 60 s |
| 1 h | 3,600 s |
| 1 d | 86,400 s |
| 1 week | 604,800 s |
| 1 month | ≈ 2,629,746 s |
| 1 year | ≈ 31,557,600 s |
