Apa itu Tenaga Kuda?

Horsepower (HP) is a unit of power that measures the rate at which work is done. It was defined by James Watt to compare steam engines with draft horses. One mechanical horsepower equals 745.7 watts or 0.7457 kilowatts. Horsepower is the standard power rating for car engines, electric motors, and industrial machinery worldwide.

All Formulas at a Glance

HP from Torque: HP = (Torque × RPM) / 5252

Torque from HP: Torque = (HP × 5252) / RPM

RPM from HP: RPM = (HP × 5252) / Torque

Konversi: 1 HP = 745.7 W = 0.7457 kW

4 Calculation Types

HP dari Torsi & RPM

Perhitungan tenaga mesin yang paling umum. Masukkan torsi (ft-lb atau N·m) dan RPM.

Torsi dari HP & RPM

Temukan berapa torsi yang dihasilkan mesin pada HP dan RPM tertentu.

RPM dari HP & Torsi

Temukan RPM di mana mesin menghasilkan tenaga puncak untuk torsi tertentu.

Konversi Satuan Daya

Convert between horsepower (HP), kilowatts (kW), and watts (W).

Cara Menggunakan Kalkulator Ini

  1. Pick a calculation type — HP from torque, torque from HP, RPM from HP, or power conversion.
  2. Enter torque in foot-pounds (ft-lb) or Newton-meters (N·m) as needed.
  3. Enter RPM or horsepower depending on the mode.
  4. Click Calculate Now and see instant results with step-by-step breakdown and chart.

Mengapa 5252?

The constant 5252 comes from unit conversions. One horsepower is 550 ft-lb per second. To go from RPM to radians per minute: (550 × 60) / (2π) ≈ 5252. This means horsepower and torque curves always cross at 5252 RPM when plotted on the same graph.

Key Conversion Factors

• 1 HP = 745,7 Watt = 0,7457 kW

• 1 kW = 1,341 HP = 1.000 Watt

• 1 ft-lb = 1,3558 N·m

• 1 N·m = 0,7376 ft-lb

Quick Examples

• 300 ft-lb pada 5252 RPM → (300 × 5252) / 5252 = 300 HP

• 200 HP pada 6000 RPM → (200 × 5252) / 6000 = 175,07 ft-lb

• 150 HP = 111,86 kW = 111,855 W

Catatan Penting

  • Semua nilai torsi dan daya harus lebih besar dari nol.
  • HP = (Torque × RPM) / 5252 applies only to rotational power in imperial units.
  • Newton-meter inputs are automatically converted to ft-lb for the formula.
  • Ini adalah nilai tenaga kuda mekanis (rem). Ada definisi HP lainnya (HP metrik, HP listrik).
