Time Converter
Convert seconds, minutes, hours, days, and more
Conversion Formula
Target = Value × (From Ratio / To Ratio)
Time conversions are linear ratio-based. Target = Value × (Source Ratio / Target Ratio). To convert hours to minutes: multiply by 3600 / 60.
Time conversion is universally needed — from calculating work hours to planning travel itineraries. Convert seconds, minutes, hours, days, weeks, months, and years.
Note that months are approximated as 30 days and years as 365 days for consistency. Actual calendar months and years vary.

Frequently Asked Questions
There are 3,600 seconds in 1 hour (60 minutes × 60 seconds). This is a fundamental time conversion used in computing, physics, and everyday scheduling.
For consistent conversion calculations, we use 30 days as the average month length. Actual months range from 28 to 31 days.
Unix time counts seconds since January 1, 1970 (UTC). It is used in programming and computing systems for timestamp representation.
There are 1,440 minutes in 1 day (24 hours × 60 minutes). This is commonly used for time management and scheduling calculations.
To convert hours to seconds, multiply by 3,600 (60 minutes × 60 seconds). For example, 2 hours × 3,600 = 7,200 seconds.
There are approximately 52.14 weeks in a standard 365-day year. A leap year has 52.29 weeks. This is used for payroll, project planning, and academic calendars.
A decade equals 10 years. A century equals 100 years (10 decades). These are used for historical time periods and long-term planning.
