The formula to calculate Rev. Per Min(RPM) is:

RPM = Horsepower * 5252 / torque;

With our online Horsepower, Torque & RPM Calculator. Power can be measured in

• Horsepower (HP),
• Watts (W) or
• Kilowatts (kW). 

Torque can be measured in 

• Pound-inch
• Pound-foot
• Newton-meter
• Newton-centimeter
• Gram-meter
• Kilogram-centimeter
• Kilogram-meter

Use our official mobile app to calculate Horsepower, Torque, and RPM. Additionally, we have hundreds of other calculators to choose from.

How do you calculate horsepower from torque and rpm? 

It is calculated as follows: H = T x rpm/5252 where

• H is horsepower,
• T is pound-feet,
• rpm is the speed of the engine, and
• 5252 is a constant that makes the units correspond.

How do you convert torque to horsepower?

The horsepower of an engine is calculated by multiplying the torque by the engine’s RPM and dividing it by 5,252.

At what rpm does torque and horsepower cross?

Gasoline engines will always have a horsepower curve and a torque curve crossing at 5,252 RPM. The answer is in this video.

The chip load refers to how much material each cutting edge removes during a cut. This is important data that may be utilised to compute new setups.

Milling machine feed rate formula

Milling machine feed rate formula is Spindle speed (RPM) * Chip load per teeth * Number of teeth.
