1 hr = 60 min
Time unit conversion guide
Convert durations between seconds, minutes, hours, days, and weeks for scheduling, billing, science problems, and everyday planning. Time units use fixed ratios, so conversions are exact when you stay within civil time units.
Project managers may need to translate estimated hours into days. Students convert seconds from a physics problem into minutes. Payroll and shift work sometimes require converting weekly hours into daily averages.
Unlike calendar months or years, the units on this page all have exact definitions (60 seconds per minute, 24 hours per day, seven days per week). Unitivo applies those ratios directly without approximating months or leap years.
Combine this tool with our distance and speed converters when solving motion problems. Site policies and support contacts are listed on the About and FAQ pages in the footer.
