Horsepower measures the rate of doing work, and this horsepower calculator finds it two ways. In the first mode, engine power follows directly from torque and rotational speed: HP = torque (lb-ft) × RPM ÷ 5252. The magic number 5,252 comes from the definition of horsepower (33,000 ft-lb per minute) and the 2π radians in a revolution, and it is also the RPM at which the horsepower and torque curves always intersect on a dyno chart. The tool reports the metric equivalent too, using 1 hp = 0.7457 kW.
As a worked example, an engine making 300 lb-ft of torque at 5,000 RPM produces 300 × 5000 ÷ 5252 ≈ 286 hp, which is about 213 kW. Because power is torque times speed, the same 300 lb-ft makes far more horsepower at high RPM than at low — which is why high-revving engines chase big peak-power figures even with modest torque.
Switch to the quarter-mile mode to estimate drag-strip performance from power and vehicle weight using Roger Huntington’s classic empirical formulas: trap speed ≈ 234 × (hp / weight)^⅓ mph and elapsed time ≈ 5.825 × (weight / hp)^⅓ seconds. A 300 hp car weighing 3,500 lb comes out around 103 mph and a 13.2-second quarter mile. These are rough guides that ignore traction, aerodynamics and driver skill, but they are a quick sanity check for a build or a way to back out power from a known trap speed.
Takon kang asring diajukake
5252 iku angka ganjil.
Horsepower is defined as 33,000 ft-lb per minute, and one revolution sweeps 2π radians. Combining the constants gives HP = torque × RPM ÷ 5252, which is also why the horsepower and torque curves always intersect at 5252 RPM on a dyno chart.
Kacamatan iki duwé jembar wewengkon 40 km².
Ing taun 1974, Roger Huntington ngenalaken formula kang nyambungake kecepatan trap lan bobot karo daya: trap speed ≈ 234 × (hp/weight)^⅓ mph. kalkulator iki ngrembakaké kanggo ngitung kecepatan trap lan wektu kang wis dilakoni saka daya lan bobot, guide kasar sing ora nganggep traksi lan aerodinamika.
Apa wae kang bisa dadi sumber daya?
Saben kilowatt jam iku 100 watt, lan saben kilowatt jam iku 1000 watt, lan saben kilowatt jam iku 10 watt.
Apa tegesé gawéan iki bisa digawé kanthi cara sing béda-béda?
Sawisé diprodhuksi, mobil iki duwé bobot 100 kg lan duwé ukuran 155 mm x 55 mm x 12 mm déné boboté mung 285 kg sajabané ukuran mesin kang kurang luwih padha karo mobil-mobil kompetitif.
Ing sisih kidul-wétan kutha iki ana segara kang ambané 400 km.
Kacepetan trap diukur kanthi akèh dhasar kubik saka horsepower saben pon, mula boboté penting kaya dayané. Sakiwa-tengené 0.1 hp saben pon (350 hp, 3,500 lb mobil) ndadèkaké sampeyan cedhak 110 mph trap; ngilangi boboté mbantu kaya nambah daya.
Apa aku bisa ngitung tenaga kuda saka kecepatan trapku?
Ing jaman biyèn, para ahli wis nganggep yèn sumbu lintang iku wujud saka garis lintang, nanging saiki wis ditetepake yèn sumbu lintang iku wujud saka garis lintang.

Ing basa Inggris, istilah "driveline" punika dipun-ginakaken kanggé ngrujuk kanggé mobil ingkang dipun-ginakaken kanggé nglampahi jarak ingkang cendhak, kados ta mobil ingkang dipun-ginakaken kanggé nglampahi jarak ingkang cendhak kanggé nglampahi jarak ingkang cendhak.
