FAQs

How do you calculate the torque of an engine?

Torque (Nm) = (9550 × Power (kW)) / RPM

Torque (lb-ft) = (5252 × HP) / RPM

This gives the twisting force produced by the engine at a specific RPM.

How much is 100 Nm of torque?

100 Newton-meters (Nm) of torque is roughly equivalent to 73.8 lb-ft of torque. This is considered moderate for small cars and motorcycles.

How much torque is required to produce 300 hp at 4600 RPM?

Torque (lb-ft) = (5252 × 300) / 4600 ≈ 342.7 lb-ft Torque (Nm) ≈ 464 Nm

How to calculate torque from HP?

Torque (lb-ft) = (5252 × HP) / RPM Torque (Nm) = (9550 × kW) / RPM

What is the easiest way to calculate torque?

Torque (lb-ft) = (Horsepower × 5252) / RPM

Is 400 Nm torque a good car?

Yes, 400 Nm of torque is considered strong for most passenger cars. It provides good acceleration and towing capability.

What is the torque of a 2.2 KW motor?

Torque (Nm) = (9550 × 2.2) / RPM

How many torque is in 1 HP?

Torque (lb-ft) = (5252 × 1) / RPM

The torque value depends on the RPM at which the horsepower is measured.
