Time Conversion — Complete Guide
Time conversions are fundamental in software development, project management, science, and everyday life. Developers frequently need to convert between milliseconds and seconds for API timeouts, between hours and days for scheduling, or between weeks and months for project planning. Scientists work with time scales ranging from milliseconds in signal processing to years in astronomical calculations.
Our Time Converter supports 8 time units from milliseconds to years. Enter any value, select the source unit, and instantly see accurate conversions. Note that months use 30-day averages and years use 365-day averages for conversion — for calendar-specific calculations, consider the exact number of days in the relevant months or years.
Quick Reference
- 1 minute = 60 seconds = 60,000 milliseconds
- 1 hour = 60 minutes = 3,600 seconds
- 1 day = 24 hours = 86,400 seconds
- 1 week = 7 days = 168 hours
- 1 year = 365 days = 8,760 hours = 31,536,000 seconds
