What this calculator does

The Time Converter lets you instantly convert between seconds, minutes, hours, days and years. Simply enter a value, choose the original time unit, select the target unit and the calculator will display the converted value together with equivalent durations in all supported units.

Whether you're calculating work hours, project durations, study time, fitness sessions or scientific measurements, this calculator provides fast and accurate conversions without manual calculations.

How the calculator works

The calculator first converts your chosen value into seconds, then converts that value into the destination unit. It also calculates equivalent values for all supported units and displays the same duration in a human-readable format.

Formula used

The following standard conversion factors are used:

• 1 Minute = 60 Seconds
• 1 Hour = 60 Minutes = 3,600 Seconds
• 1 Day = 24 Hours = 86,400 Seconds
• 1 Year = 365 Days = 31,536,000 Seconds

The calculator automatically chooses whether to multiply or divide depending on the selected conversion.

Worked examples

Convert 20 Hours to Seconds

• 20 × 3,600 = 72,000 Seconds
• Equivalent duration: 20 Hours

Convert 90 Minutes to Hours

• 90 ÷ 60 = 1.5 Hours

Convert 3 Days to Hours

• 3 × 24 = 72 Hours

Convert 2 Years to Days

• 2 × 365 = 730 Days

Equivalent Duration

Unlike many basic converters, this calculator also shows the converted value as an equivalent duration.

For example:

• 100,000 Seconds = 1 Day, 3 Hours, 46 Minutes and 40 Seconds
• 20 Hours = 20 Hours
• 730 Days = 2 Years

This makes it much easier to understand long periods of time at a glance.

Common uses

• Employee working hours and overtime calculations
• Project planning and scheduling
• Travel planning
• Exercise and fitness tracking
• Cooking and baking timers
• Scientific calculations
• Engineering projects
• Video and audio production
• Software development and system logs

Common mistakes

• Assuming 100 minutes equals 1 hour.
• Confusing decimal hours with hours and minutes.
• Using 365.25 days instead of 365 days when a standard year is required.
• Mixing calendar dates with elapsed time.

For example, 1.5 hours is 1 hour and 30 minutes, not 1 hour and 50 minutes.
