1 hr = 60 min
About time durations
These conversions cover civil durations with exact ratios: seconds, minutes, hours, days and weeks—not calendar months or leap years.
In short
There are 60 seconds in a minute, 60 minutes in an hour, 24 hours in a day, and 7 days in a week—exact civil-time ratios.
Work & billing hours
Contracts and timesheets jump between hours and days. An 8-hour day and a 40-hour week are common baselines: 40 hours = 2,400 minutes. Convert overtime blocks into hours before comparing rates.
Study & exam timing
Practice tests list minutes; research papers may report seconds for reaction times. 90 minutes = 1.5 hours; 10,000 seconds ≈ 2.78 hours. Match the unit to the scoring rubric or lab protocol.
Media length
Podcasts, videos and audiobooks display h:mm:ss while analytics dashboards sometimes total minutes or seconds. A 45-minute episode is 2,700 seconds—useful when estimating storage or attention budgets.
Science & sensors
Data loggers sample in seconds or milliseconds (convert ms to s by dividing by 1,000). Keep long experiment runtimes in hours or days so charts stay readable, then drop back to seconds for formulas.
What this page does not do
Months and years vary in length; time zones and daylight-saving shifts are calendar problems, not fixed ratios. For those, use a date/time library or calendar tool—this converter stays on exact 60/24/7 relationships.
