Frequently asked questions
What is the relationship between torque and power?
P = τ × ω, where ω is the angular velocity in radians per second.
How do you convert RPM to rad/s?
ω = RPM × 2π / 60.
What units does it use?
N·m for torque, RPM for rotational speed, and kW when entering power.
Does it also show CV?
Yes, when calculating power.
