Time Converter

How to use the Time Converter

Convert common duration units from milliseconds through weeks without manually multiplying or dividing conversion factors.

Convert durations among seconds, minutes, hours, days, and selected larger units. It is intended for fixed-duration arithmetic rather than calendar months with variable lengths.

The conversion runs locally using the stated factors or formulas. Keep enough precision for the task and verify regulated or engineering work against its controlling standard.

1. Enter the duration value.
2. Choose the source and destination units.
3. Fieldlet converts through seconds and displays the equivalent duration.

Worked examples

How the result is produced

The tool converts to a seconds base using fixed factors. Days are treated as 24 hours; calendar dates, daylight-saving changes, and variable months require date-aware tools instead.

• 1 minute = 60 seconds
• 1 hour = 3,600 seconds
• 1 fixed day = 86,400 seconds

Fixed durations versus calendar periods

Seconds, minutes, hours, days, and weeks can be represented with fixed factors here. Calendar months and years vary in length, while civil days can also be affected by clock changes when a location and date are involved.

• 1 minute = 60 seconds.
• 1 day = 86,400 seconds as a fixed duration.
• Use a date calculator for calendar months or years.

Limitations and common mistakes

• A calendar month and year are not fixed numbers of seconds.
• Civil time intervals across clock changes require a date, time zone, and governing convention.
