Enter your hour (hr) value, select hr as the source unit — the minute (min) result appears instantly. Formula: hr × 60 = min. Example: 2.5 hr = 150 minutes. One hour = 60 minutes = 3,600 seconds (s) exactly. Copy the result with one click — no typing needed.

1 minute (min) = 60 seconds (s) exactly. 1 hour (hr) = 3,600 seconds (60 min × 60 s). Common references: 90 seconds = 1.5 min; 5 minutes = 300 s; 30 minutes = 1,800 s; 1 hour 30 minutes = 5,400 s. In milliseconds: 1 minute = 60,000 ms; 1 hour = 3,600,000 ms.

Minutes to seconds: min × 60 = s. Example: 45 min = 2,700 s. Seconds to minutes: s ÷ 60 = min. Example: 90 s = 1.5 min. Decimal minutes work too: 1.75 min = 105 s. This conversion is common in sports timing (race splits), cooking timers, and workout intervals.

Hours to seconds: hr × 3,600 = s. Example: 2 hr = 7,200 s. Seconds to hours: s ÷ 3,600 = hr. Example: 9,000 s = 2.5 hr. The factor 3,600 comes from 60 minutes × 60 seconds. In milliseconds: 1 hr = 3,600,000 ms. Useful for SLA uptime calculations, physics problems, and data transfer rate conversions.

Days to hours: d × 24 = hr. Example: 3 days = 72 hours. Hours to days: hr ÷ 24 = d. Example: 36 hr = 1.5 days. In minutes: 1 day = 1,440 min. In seconds: 1 day = 86,400 s. The 86,400-second day is a fixed value used in Unix timestamps, SLA calculations, and astronomy.

1 day = 24 hours (hr). 1 week = 168 hours (7 days × 24 hr). In minutes: 1 day = 1,440 min; 1 week = 10,080 min. In seconds: 1 day = 86,400 s; 1 week = 604,800 s. A standard 40-hour work week = 5 days × 8 hr, leaving 128 non-working hours in that same week.

Weeks to days: wk × 7 = d. Example: 3 weeks = 21 days. Days to weeks: d ÷ 7 = wk. Example: 45 d = 6.43 weeks. In hours: 1 week = 168 hr. Common use cases: sprint planning (2-week sprint = 14 days = 336 working-and-non-working hours), school terms, project milestone windows.

Months to days: mo × 30.4375 = d (average). Example: 6 months ≈ 182.6 days. Years to days: yr × 365.25 = d (Julian year, accounting for leap years). Example: 2 years = 730.5 days. Note: calendar months range from 28–31 days. For precise contract or legal date calculations, count exact calendar days rather than using averages.

1 second (s) = 1,000 milliseconds (ms). 1 minute = 60,000 ms. 1 hour = 3,600,000 ms. In the other direction: 1 ms = 0.001 s = 0.001/60 min ≈ 0.0000167 min. Milliseconds are the standard unit for web performance (page load times), network latency, and JavaScript animation frames (one frame at 60fps ≈ 16.67 ms).

UntangleTools Time Converter supports: nanosecond (ns), microsecond (μs), millisecond (ms), second (s), minute (min), hour (hr), day (d), week (wk), month (mo), year (yr). Enter any value, select the source unit, and all outputs appear simultaneously. One-click copy per result. Free, no login, mobile-friendly at untangletools.com/unit/category/time.

Three steps: (1) Type or paste a time value — integers and decimals both work (e.g., 1.5 hr, 90 min, 7200 s). (2) Select the source unit from the dropdown: ns, μs, ms, s, min, hr, d, wk, mo, or yr. (3) All other units update instantly. Tap the Copy button on any row to copy that value directly to your clipboard.

Yes. The converter handles the full span from nanoseconds (ns) to years (yr) in one input. Example: enter 3,600,000 ms → instantly see it equals 1 hr, 60 min, 3,600 s, 0.0417 days. Or enter 2 years → see it as 730.5 days, 17,532 hr, 1,051,920 min, 63,115,200 s. No range restriction on inputs.

Yes — all of them. Full unit support: nanosecond (ns), microsecond (μs), millisecond (ms), second (s), minute (min), hour (hr), day (d), week (wk), month (mo, ≈30.4375 d average), year (yr, 365.25 d Julian). Every unit is selectable as source input. All others output simultaneously with one-click copy per row.

Yes. Decimal inputs are fully supported. Examples: 1.5 hr → 90 min, 5,400 s; 0.75 hr → 45 min; 7.5 hr → 450 min (a typical work shift). In reverse: 45 min → 0.75 hr. Decimal hours (also called "hours and hundredths") are used in payroll systems, timesheets, and engineering calculations.

Yes. All factors use exact or internationally standardised values: 1 min = 60 s exactly; 1 hr = 3,600 s; 1 day = 86,400 s; 1 Julian year = 31,557,600 s (365.25 × 86,400). Month values use the mean calendar month of 30.4375 days. Full 64-bit floating-point precision. Completely free at untangletools.com/unit/category/time — no account.

Multiply hours by 60: hr × 60 = min. Examples: 1 hr = 60 min; 2.5 hr = 150 min; 0.5 hr = 30 min. In reverse: min ÷ 60 = hr. The factor of 60 comes from the Babylonian sexagesimal (base-60) numeral system, which is why we have 60 seconds in a minute and 60 minutes in an hour — a system over 3,000 years old.

90 seconds (s) = 1.5 minutes (min) = 1 minute 30 seconds. 120 seconds = 2 minutes exactly. Formula: s ÷ 60 = min. More examples: 45 s = 0.75 min; 150 s = 2.5 min; 600 s = 10 min. In milliseconds: 90 s = 90,000 ms; 120 s = 120,000 ms. Common context: a 90-second workout interval = 1 min 30 sec on a gym timer.

Divide total minutes by 60: min ÷ 60 = hr. Example: 450 minutes of study = 7.5 hours. For mixed logs: add all minutes first, then divide once. Example: 90 + 75 + 45 + 120 = 330 min ÷ 60 = 5.5 hr. In payroll: 5.5 hr = 5 hours 30 minutes. To convert back to hr:min format, take the decimal × 60 (0.5 × 60 = 30 min).

To get minutes past midnight from a 24-hr time: hours × 60 + minutes = total minutes. Example: 14:30 = (14 × 60) + 30 = 870 minutes past midnight. For 12-hr: convert PM hours by adding 12 first (2:30 PM = 14:30 → 870 min). Back to time: 870 ÷ 60 = 14 hr remainder 30 min = 14:30. Useful in scheduling algorithms, shift-gap calculations, and database time storage.

For payroll: hr × 60 = min then × 60 for seconds. Example: 7.5-hr shift = 450 minutes = 27,000 seconds. For a 40-hr week: 40 × 3,600 = 144,000 seconds. Decimal time: 7 hr 45 min = 7 + (45/60) = 7.75 hr (used in many payroll systems). Monthly hours: 52 wk × 40 hr ÷ 12 = 173.33 hours/month average.

hh:mm:ss to total seconds: (hh × 3,600) + (mm × 60) + ss. Example: 1:15:30 = 3,600 + 900 + 30 = 4,530 s. Total seconds back to hh:mm:ss: hours = ⌊s/3600⌋, minutes = ⌊(s mod 3600)/60⌋, seconds = s mod 60. mm:ss to seconds: (mm × 60) + ss. Example: 4:33 = 273 s. This pattern is essential for video timestamps, sports timing, and log parsing.

Duration is a fixed quantity of time — e.g., "the meeting lasts 90 minutes." Elapsed time is measured from a start point — e.g., "45 minutes have elapsed since the meeting started." Both express the same unit (minutes / min, hours / hr, seconds / s) but duration describes total span while elapsed time describes progress within it. Converters like this one handle both — enter the value regardless of which concept it represents.

Yes to nanoseconds (ns) and microseconds (μs) — both are in the unit dropdown. For reference: 1 μs = 0.000001 s = 1,000 ns; 1 ns = 0.000000001 s. Fortnights: not a dedicated unit, but 1 fortnight = 2 weeks = 14 days = 336 hours = 1,209,600 seconds — enter 2 in the weeks field to get the full breakdown. Decades and centuries can be entered as multiples of years (1 decade = 10 yr).
