Unit Converters
Hours to Minutes Converter (hr to min)
minutes = hours × 60.
Multiply hours by 60. A 1.5 hour meeting is 90 minutes. Decimal hours on a timesheet (7.25 h) are 435 minutes, not 7 hours 25 minutes — that mix-up is how payroll tickets start.

- 2minutes = hours × 60.
- 3Worked case: 2.25 h → 135 min. 8 h shift → 480 min.
- 4Check which dictionary the other person is using — US or UK, decimal or 1,024 — then trust the number.
Governing formula
minutes = hours × 60.
2.25 h → 135 min. 8 h shift → 480 min.
Example: set Hours = 1.5, then read the result.
Variable definitions

Hours
The “Hours” field. Default 1.5; typical range 0–10000.
- The conversion (minutes = hours × 60.) does not pick US vs UK gallons, SI vs binary megabytes, or Mach at altitude for you. Read the footnote on the page.

Frequently Asked Questions
1:30 is 1.5 h = 90 min. 1.30 h is 78 min. The colon matters.

- Minutes to HoursDivide minutes by 60. 90 minutes is 1.5 h, not 1.90 h. Timesheets that type 1.5 vs 1:30 are the same trap in reverse of the hours-to-minutes page.
- SI Second Prefix ConverterMilliseconds, microseconds, nanoseconds, and the less-loved kilosecond all sit on the same second. A 250 ms camera shutter is 0.25 s. A CPU cycle in nanoseconds is still a second with nine zeros parked in front. Minutes and hours are sexagesimal, not SI prefixes — use those pages for 60-based time.
- Appliance Running CostCost = watts × hours / 1000 × $/kWh. A 1,500 W space heater for 4 hours at $0.16/kWh is $0.96. The supply rate on the bill is the one that matters, not a national average.
- Audio Bitrate StorageUncompressed-ish math: size in bytes = bitrate (bits/s) × seconds ÷ 8. A 320 kbps MP3, 4 minutes, is about 9.6 MB. CD audio 1,411 kbps is 10.6 MB per minute. Variable bitrate files will miss this — it is an average-rate sketch.
- BTU to kWhUS furnaces and AC still speak BTU. Electricity speaks kWh. Divide BTU by 3,412. 12,000 BTU/h is a “1 ton” of cooling and 3.52 kW if it ran an hour — note the /h: that is power. This field is energy (BTU, not BTU/h).
- Data Transfer TimeHow long to move a file if the pipe is what they claimed. Time in seconds = size in GB × 8,000 ÷ Mbps. A 4.7 GB DVD over 50 Mbps is about 12.5 minutes before Wi-Fi and TCP take a cut. This is a ceiling on hope, not a promise.

Unit Converters
A 5K is 5,000 meters, not 5 kilometers on the nose if your watch is sloppy. Divide meters by 1,000. Track races, building plans, and “how far was that hike” all live in this split.
Feet to Meters
Unit Converters
US height, ceiling height, and lumber still arrive in feet. Meter plans do not. One foot is exactly 0.3048 m — not “about a third.” Use this when a listing says 10 ft ceilings and the architect works in meters.
Inches to Centimeters
Unit Converters
Monitor diagonals, waist measurements, and photo prints still come in inches. Clothing charts in Europe come in cm. Multiply inches by 2.54. That factor is exact, not a kitchen guess.

Very usable on mobile. Would love a save/export option later, but the math feels solid.
