How do you calculate horsepower from torque and RPM?

Horsepower (hp) = [Torque (lb·ft) × RPM] / 5252. In SI units, Power (Watts) = Torque (N·m) × [RPM × 2π / 60]. For example, an engine producing 400 N·m (295 lb·ft) of torque at 5,252 RPM generates exactly 295 hp (220 kW).

Why does horsepower equal torque at 5252 RPM?

In imperial units, 1 horsepower is defined as 33,000 ft·lb/min. Since one revolution covers 2π radians, dividing 33,000 by 2π yields 5252.11. Therefore, when rotating at 5,252 RPM, torque in lb·ft numerically equals horsepower.

How to Convert Kilogram-force centimeter to Kilogram-force meter

Converting Kilogram-force centimeter (kgf·cm) to Kilogram-force meter (kgf·m) is a core calculation in Torque and Moment of Force, which measures the rotational or twisting force acting upon an object about an axis, pivot, or fulcrum. Both units reside within the International System of Units (SI) and share an identical physical dimension vector ([M L² T⁻²]), separated strictly by a decimal order-of-magnitude factor (10^-2). Because this shift involves integer powers of 10, the conversion is mathematically exact and free from decimal rounding or irrational fractional loss. Exactly 1 Kilogram-force centimeter equals 0.01 Kilogram-force meter.

Mathematical Conversion Derivation via Coherent SI Base Unit

Under the International System of Quantities (ISQ), dimensional conversion between non-SI units is rigorously resolved by bridging through the coherent SI base unit (newton meter (N·m)) without arbitrary rounding:

V_{\text{target}} = V_{\text{source}} \times \left( \frac{k_{\text{source} \to \text{SI}}}{k_{\text{target} \to \text{SI}}} \right)

Universal Dimensional Conversion Law (ISO 80000 / NIST SP 811)

1. Source SI Bridge (k_source):1 kgf·cm = 0.0980665 newton meter (N·m)

2. Target SI Bridge (k_target):1 kgf·m = 9.80665 newton meter (N·m)

Step-by-step substitution for Kilogram-force centimeter → Kilogram-force meter:V(kgf·m) = V(kgf·cm) × ( 0.0980665 / 9.80665 ) = V(kgf·cm) × 0.01

Mathematical FormulaValue in Kilogram-force meter = Value in Kilogram-force centimeter × 0.01Direct computational formula applied for standard conversion.

Worked Example

To convert 50 Kilogram-force centimeter (kgf·cm) to Kilogram-force meter (kgf·m): multiply 50 by 0.01 to get 0.5 kgf·m. At an industrial engineering scale, 100 kgf·cm converts to 1 kgf·m.

Inverse check: 1 kgf·m = 100 kgf·cm.

Frequently Asked Questions

There are exactly 0.01 kilogram-force meters (kgf·m) in 1 kilogram-force centimeter (kgf·cm). To calculate larger amounts manually, simply multiply your total number of kilogram-force centimeters by the conversion multiplier of 0.01.

The mathematical formula to convert kilogram-force centimeters to kilogram-force meters is: [value] * 0.01 = kilogram-force meters. Rather than doing the math manually, you can use our high-precision online calculator to process this exact equation instantly without rounding errors.

To perform the reverse calculation from kilogram-force meters back to kilogram-force centimeters, you must divide your starting value by 0.01. Our bidirectional tool automatically computes this inverse equation the moment you type into the kilogram-force meter input field.

1 Kilogram-force meter is larger than 1 Kilogram-force centimeter. Specifically, 1 Kilogram-force centimeter equals 0.01 kilogram-force meters, meaning 1 Kilogram-force meter is 100 times larger than 1 Kilogram-force centimeter (a difference of 2.00 orders of magnitude). Expressing measurements in kilogram-force centimeters requires a larger numerical value to represent the equivalent physical magnitude.

A typical robotics hobby RC digital servo motor stall torque rating measures 15 kgf·cm, which corresponds to 0.15 kgf·m (Kilogram-force meter).

There is exactly 0.01 kgf·m in 1 kgf·cm.

The mathematical formula is V(kgf·m) = V(kgf·cm) × 0.01.

The reverse formula is V(kgf·cm) = V(kgf·m) × 100.

Kilogram-force meters are commonly used in macro-scale engineering such as automotive lug nut torque and heavy machinery specification, whereas kgf·cm is reserved for smaller mechanisms like stepper motors.
