Time unit converter
Type a duration with its unit, then pick the result format you want. Enter "90 min" and choose Hour to get 1.5 Hours. The same input can be read as 90 minutes, 1.5 hours, or 5400 seconds just by switching formats. The converter handles minutes, hours, seconds, days, weeks, and milliseconds in one line.
Most time conversions are simple division or multiplication, but the right divisor is easy to forget under pressure. Is an hour 60 minutes or 100? How many hours sit in three days? This converter holds the rules so you do not have to. You type the duration the way you would say it, choose how the answer should read, and the calculator does the math. Each pair below also works as a quick reference you can read without typing anything.
