Power to Mass Ratio Calculator

Formula

To calculate the Power to Mass Ratio (R):

\[ R = \frac{P}{M} \]

Where:

\(R\) is the power to mass ratio
\(P\) is the power output (W or hp)
\(M\) is the mass (kg or lbs)

What is Power to Mass Ratio?

The power to mass ratio is a measure of the performance of an object or vehicle, indicating how much power it can produce per unit of mass. It is commonly used to compare the performance of different vehicles or machines.

Example Calculation 1

Let's assume the following values:

Power Output = 200 hp
Mass = 1500 lbs

Using the formula:

\[ R = \frac{200}{1500} = 0.13 \text{ hp/lb} \]

The power to mass ratio is 0.13 hp/lb.

Example Calculation 2

Let's assume the following values:

Power Output = 150 kW
Mass = 1000 kg

Using the formula:

\[ R = \frac{150}{1000} = 0.15 \text{ kW/kg} \]

The power to mass ratio is 0.15 kW/kg.
