Time Converter — Convert Between Time Units
The Time Converter is a free, instant-use tool for converting between 12 time units from nanoseconds to centuries, with a human-readable time breakdown feature. Whether you're calculating durations for programming, project management, science, or everyday life, this tool provides accurate real-time conversions.
All calculations run entirely in your browser. No data is sent to any server.
Supported Units
- Nanosecond (ns) — One billionth of a second. CPU clock cycles operate in nanoseconds. Light travels about 30 cm in 1 ns. Used in computing, electronics, and physics.
- Microsecond (μs) — One millionth of a second. Used for network latency, audio sampling, and sensor response times.
- Millisecond (ms) — One thousandth of a second. Used for animation frame rates (16.67 ms for 60fps), API response times, and human reaction measurements (~250 ms average).
- Second (s) — The SI base unit of time. Defined by the cesium-133 atomic transition (9,192,631,770 oscillations).
- Minute (min) — 60 seconds. The standard short-duration unit for everyday use.
- Hour (h) — 3,600 seconds. Used for work schedules, travel times, and rate calculations.
- Day (d) — 86,400 seconds. Based on the solar day. Used for deadlines, project planning, and duration calculations.
- Week (wk) — 7 days = 604,800 seconds. Standard business and planning unit.
- Month (mo) — 30 days (approximation). Used for billing cycles, subscriptions, and project timelines.
- Year (yr) — 365 days = 31,536,000 seconds. The standard annual cycle for calendars and age.
- Decade — 10 years. Used for historical periods and long-term planning.
- Century — 100 years. Used for historical timescales.
Human-Readable Breakdown
The tool automatically shows a human-friendly breakdown of the time value. For example, entering 100,000 seconds shows "1d 3h 46m 40s" — much easier to understand than a raw number.
Key Conversion Factors
- 1 minute = 60 s = 60,000 ms
- 1 hour = 60 min = 3,600 s
- 1 day = 24 h = 1,440 min = 86,400 s
- 1 week = 7 d = 168 h = 604,800 s
- 1 year = 365 d = 8,760 h = 31,536,000 s
