Time Facts
Interesting Time Measurements:
- 1 Planck Time: ~5.39×10⁻⁴⁴s (theoretically smallest time measurement)
- 1 Attosecond: 1×10⁻¹⁸s (time for light to travel the length of 3 hydrogen atoms)
- Human Reaction Time: ~0.25s (average visual stimulus response)
- 1 Lunar Month: ~29.53 days (moon's synodic period)
- 1 Gregorian Year: 365.2425 days (average including leap years)
Conversion Formulas:
- Seconds to Minutes: min = s ÷ 60
- Minutes to Hours: h = min ÷ 60
- Hours to Days: d = h ÷ 24
- Days to Weeks: week = d ÷ 7
- Months to Years: year = month ÷ 12
- Nanoseconds to Seconds: s = ns × 10⁻⁹
Time Conversion Tables
Second Conversion Table
| Unit | Seconds (s) | Conversion Formula |
|---|---|---|
| Millisecond (ms) | 0.001 | 1 s = 1000 ms |
| Microsecond (µs) | 0.000001 | 1 s = 1,000,000 µs |
| Nanosecond (ns) | 0.000000001 | 1 s = 1,000,000,000 ns |
| Picosecond (ps) | 0.000000000001 | 1 s = 1,000,000,000,000 ps |
| Minute (min) | 60 | 1 min = 60 s |
| Hour (h) | 3,600 | 1 h = 3,600 s |
| Day (d) | 86,400 | 1 d = 86,400 s |
| Week | 604,800 | 1 week = 604,800 s |
| Month (avg) | 2,629,800 | 1 month ≈ 2,629,800 s |
| Year (avg) | 31,557,600 | 1 year ≈ 31,557,600 s |
Common Time Conversions
| Conversion | Formula | Example |
|---|---|---|
| Minutes to Seconds | s = min × 60 | 5 min = 300 s |
| Hours to Minutes | min = h × 60 | 2 h = 120 min |
| Days to Hours | h = d × 24 | 3 d = 72 h |
| Weeks to Days | d = week × 7 | 2 weeks = 14 d |
| Years to Days | d = year × 365.2425 | 1 year ≈ 365.2425 d |
| Milliseconds to Microseconds | µs = ms × 1,000 | 10 ms = 10,000 µs |
| Nanoseconds to Picoseconds | ps = ns × 1,000 | 5 ns = 5,000 ps |

Frequently Asked Questions
A standard year has 365 days, while a leap year has 366 days with February 29 as the extra day. Leap years occur every 4 years to account for the Earth's orbit around the Sun taking approximately 365.2425 days. However, years divisible by 100 are not leap years unless they're also divisible by 400 (e.g., 2000 was a leap year but 1900 was not).
Different year measurements serve different purposes:
- Tropical year: Time between vernal equinoxes (365.24219 days) - used for calendars
- Sidereal year: Earth's orbit relative to distant stars (365.25636 days) - used in astronomy
- Anomalistic year: Time between perihelions (365.25964 days) - studies Earth's elliptical orbit
- Julian year: Exactly 365.25 days (used in scientific calculations)
The tool uses average month durations (30.44 days/month or 2,629,800 seconds/month) for simplicity. Actual month lengths vary:
- 28-31 days in Gregorian calendar months
- ~29.53 days for lunar months
- Different lengths in various calendar systems
Ultra-small time measurements are essential in:
- Nanoseconds (10⁻⁹s): Computer processor operations, RAM access times
- Picoseconds (10⁻¹²s): Light travels ~0.3mm, used in laser physics
- Femtoseconds (10⁻¹⁵s): Molecular vibrations, chemical reaction studies
- Attoseconds (10⁻¹⁸s): Electron movements in atoms
- Planck time (10⁻⁴⁴s): Theoretical quantum gravity research
This tool supports many specialized time units. Here are some conversion factors:
- 1 fortnight = 2 weeks = 1,209,600 seconds
- 1 decade = 10 years ≈ 315,576,000 seconds
- 1 century = 100 years ≈ 3,155,760,000 seconds
- 1 millennium = 1,000 years ≈ 31,557,600,000 seconds
- 1 sidereal day ≈ 86,164.09 seconds (vs solar day's 86,400)

This converter saved me so much time on my physics homework! The femtosecond conversions were particularly helpful for my quantum mechanics project.

As an astronomy instructor, I appreciate the inclusion of sidereal time units. Most converters don't include these specialized measurements. Excellent resource!

I use this weekly for work when converting between milliseconds and microseconds in our performance metrics. The formula display helps me verify my manual calculations.
