Timers, timesheets, recipes, and workout logs all need a reliable time conversion chart when the number on the screen is not the unit you need to report. This guide covers core duration math, then points to separate blogs for clock formats, time zones, and pool-course times.

No sign-up required. ## What time conversion covers (duration, not clock face) Here, time conversion means rewriting a length of time: how long something lasts. Sixty seconds make a minute; sixty minutes make an hour; twenty-four hours make a day. That is different from reading a 24-hour clock, shifting a meeting across time zones, or comparing swim times between pool lengths, those topics have their own guides linked below. Most duration factors are exact integers. The exceptions are calendar-ish units (months, years) where “average” lengths appear in converters, use those carefully for payroll or legal deadlines. ## Plain-language time formulas - Minutes ↔ seconds: multiply minutes by 60. Divide seconds by 60 for minutes. - Hours ↔ minutes: multiply hours by 60. Divide minutes by 60 for hours. - Hours ↔ seconds: multiply hours by 3,600. - Days ↔ hours: multiply days by 24. - Weeks ↔ days: multiply weeks by 7. - Years ↔ days (common converter average): often 365.25 days per year for long-span estimates. ## Time conversion chart Unit Equals 1 minute 60 seconds 1 hour 60 minutes / 3,600 seconds 1 day 24 hours / 1,440 minutes 1 week 7 days / 168 hours 1 year (avg.) ≈ 365.25 days ### Quick duration table Input Result 90 seconds 1.5 minutes 150 minutes 2.5 hours 36 hours 1.5 days 10 days ≈ 1.43 weeks 2 weeks 336 hours ## Worked examples ### Example 1, podcast length for a schedule An episode is **2,700** seconds long. In minutes: 2,700 ÷ 60 = **45 minutes**. In hours: 45 ÷ 60 = **0.75 hours**. ### Example 2, timesheet overtime block You logged **11.25 hours** on a shift. In minutes: 11.25 × 60 = **675 minutes**. Report the decimal hours your payroll system expects, or convert once and keep the same unit end-to-end. ### Example 3, project buffer in days A task estimate is **56 hours** of focused work. In days at 8 hours/day: 56 ÷ 8 = **7 workdays** (not 56 ÷ 24 calendar days). ## Common time conversion mistakes - Treating decimal hours as hours:minutes. 1.5 hours is 1 hour 30 minutes, not 1:50. - Using 30 days for every month when a deadline is calendar-specific. - Mixing stopwatch seconds with clock time-of-day without labeling the unit. - Converting work hours with 24-hour days when the estimate assumed an 8-hour workday. ## Related topics (bridge only) These angles have dedicated blogs, use them when that is the real question: - Military time explained, 24-hour clock reading and AM/PM conversion - Time zone conversion guide, PST, EST, GMT/UTC offsets and meeting planning - Swimming time conversions, SCY vs LCM course standards ## Time converter tools Use the [Time Converter](https://shoutingnow.com/tools/time-converter/) for any duration pair, or open a focused tool: - Hours to Seconds Converter - Minutes to Hours Converter - Minutes to Days Converter ## Related reading - Military time explained, 24-hour clock reading and AM/PM conversion - Time zone conversion guide, PST, EST, GMT/UTC offsets - Swimming time conversions, SCY vs LCM course standards - Unit conversion chart & calculator guide, full category map ## Frequently Asked Questions ### How do I convert hours to minutes? Multiply hours by 60, so 2.5 hours becomes 150 minutes. The [Time Converter](https://shoutingnow.com/tools/time-converter/) also handles seconds, days, and weeks if you need those too. ### How many seconds are in one hour? 3,600 seconds (60 × 60). A 45-minute podcast, for reference, runs 2,700 seconds. ### Is 1.5 hours the same as 1:50? They are not, and it is an easy mix-up. 1.5 hours means 1 hour 30 minutes, while 1:50 usually reads as one hour fifty minutes, about 1.833 hours. ### Does this guide cover military time or time zones? Only in passing. [Military time explained](https://shoutingnow.com/blog/military-time-explained/) covers reading the 24-hour clock, and the [time zone conversion guide](https://shoutingnow.com/blog/time-zone-conversion-guide/) covers PST/EST/UTC offsets. ### Can I convert weeks to hours? Sure, one week is 168 hours (7 × 24), so two weeks comes to 336. Just confirm whether your project estimate needs calendar hours or workday hours before you use the number. ### Are ShoutingNow time converters free?
