Enter the power of your engine and the total weight of your vehicle to calculate the power-to-weight ratio (PWR).
Use this power to weight ratio calculator to recognize the real performance ability of your automobile, gadget, or maybe your self as a bike owner. The calculator is a helpful choice for evaluating the electricity (ability to do work) of something to its weight (mass).
1 . Calculate the strength-to-weight ratio of a car with a weight of three,000 kilos and an engine electricity of 350 horsepower
Solution:
for the reason that:
with the aid of including values in the strength-to-weight ratio (PWR) formula:
=\(\frac{350}{3000}\)
= 0.11667 (hp(l)/lb)
2. find power to weight ratio of a cyclist who weighs 60 kg and might sustain a electricity output of 210 watts.
Solution:
Given that:
positioned values in the electricity-to-weight ratio formula:
=\(\frac{210}{60}\) = 3.5 W/Kg
To quickly get the PWR values, use the electricity to weight calculator.

It depends on the particular software and motor layout. but, permanent magnet cars are usually taken into consideration to have the best electricity-to-weight ratio because of their high torque, density, and relatively lightweight creation.
the automobile electricity to weight ratio facilitates to recognise how fast a vehicle can boost up. whilst PWR is a crucial factor, it's now not the handiest issue that determines acceleration.
