Time Converter

What is the Time Converter?

Convert any time unit to all others at once — s, min, h, d, wk, yr. Converting between seconds, minutes, hours, days, weeks and years helps with schedules, payroll, project planning and science problems.

How to use the Time Converter

1. Enter your value, your from unit.
2. Results update automatically as you type; you can also press Calculate.
3. Read the output: second (s), minute (min), hour (h), day (d).
4. Check the chart to see how the conversion scales.

Formula and method

Worked example

With value = 1, from unit = Second (s), the Time Converter returns second (s): 1 s; minute (min): 0.0166666666667 min; hour (h): 0.000277777777778 h.

When an all-in-one time converter helps

A project manager estimates a task at 2,400 minutes and needs it in working days for a plan. Converting gives 40 hours, or five 8-hour days.

A student converts a radioactive half-life given in seconds into days to make the number easier to understand.

Watch out for these mix-ups

• Assuming every month has the same length.
• Ignoring leap years.
• Mixing decimal hours with clock time.
• Rounding long durations early.

Tips for better results

• Use exact conversions where possible.
• Check calendar-based durations separately.
• Convert decimal hours carefully.

💡 Practical tip: A year is about 365.25 days on average because of leap years.
