Kilowatts to Horsepower Converter (kW to hp)
hp = kW × 1.341022. (1 hp = 0.7457 kW.)
Divide kW by 0.7457 (or multiply by 1.341). A 100 kW electric motor is 134 hp. EV brochures already did this; ICE dyno sheets sometimes did not. Metric PS is 1.36 hp per kW — close enough to start a fight.

- 2hp = kW × 1.341022. (1 hp = 0.7457 kW.)
- 3Worked case: 75 kW → 100.6 hp. 250 kW → 335 hp.
- 4Check which dictionary the other person is using — US or UK, decimal or 1,024 — then trust the number.
Governing formula
hp = kW × 1.341022. (1 hp = 0.7457 kW.)
75 kW → 100.6 hp. 250 kW → 335 hp.

Kilowatts
The “Kilowatts” field. Default 100; typical range 0–10000.
- The conversion (hp = kW × 1.341022. (1 hp = 0.7457 kW.)) does not pick US vs UK gallons, SI vs binary megabytes, or Mach at altitude for you. Read the footnote on the page.
- Nothing here is uploaded for the calculation itself.

- Horsepower to WattsMechanical horsepower is 745.7 W. A 150 hp engine is 112 kW. Metric PS is 735.5 W — close, not the same. Peak dyno hp is not what the wheels see. Convert the number on the spec sheet, then stay humble.
- SI Watt Prefix ConverterPhone chargers in watts, homes in kilowatts, plants in megawatts, grids in gigawatts. A 1.5 kW kettle is 1,500 W. Terawatts show up in climate-scale diagrams, not in a breaker panel.
- Acres to HectaresUS farm ads in acres, EU paperwork in hectares. Divide acres by 2.471. Ten acres is 4.05 ha. A 160-acre quarter-section is 64.7 ha.
- Acres to Square FeetUS land: one acre is 43,560 ft², a chain-and-furlong leftover that refused to die. A quarter-acre lot is 10,890 ft². Multiply acres by 43,560. Soccer-field metaphors are not a survey.
- 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.

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.
