Power and Weight:

The time rate of doing work is called power. On the other hand, The measurement of the force of gravity that acts on an object is called the weight of the body.

Power to Weight Ratio:

It is the measure of how much power is produced per unit weight by the vehicle.

Units of the Power to Weight Ratio:

Generally, horsepower per pound (hp/lb) and kilowatt per kilogram (kW/kg) are two common units of power to weight ratio.

Let’s talk about the basics of the weight to power ratio concept. Measurement of the actual performance of any engine or power source is known as the power to weight ratio of the vehicle. First, keep in mind that all the vehicles have different power and weight figures that could be calculated with this power to weight calculator.

Commonly, power-to-weight ratio calculation is entirely applied to the engine and power sources to enable the comparison of one unit or design to another.
Power to weight ratio comes when a vehicle’s power is divided by its weight (or mass)
You can calculate the value of horsepower per pound (hp/lb) with this best and fast online hp to weight ratio calculator.

Power to Weight Ratio (PWR) Formula:

The power to weight ratio calculator uses the following formulas to calculate the power to weight ratios of moving vehicles.

PWR (hp/lb) = P (hp) / WT (lb)

PWR (W/kg) = P (W) / WT (kg)

Calculating power to weight ratio (PWR)

Calculate power to weight ratio is simple and convenient, it just divides the power output of a vehicle by its weight.

For example:

If you have a car that weighs 3000 pounds and has 350 hp. Find the power to the ratio of the car.

Solution:

Formula =hp/pounds

=350/3000

=8.571 Ans.

Power to Weight Ratio Chart:

Now we discuss a table chart of power to weight ratio that clarifies your concept, and you can verify these values with respect to this horsepower to weight ratio calculator.

How to Find Power to Weight Ratio?

Let’s see the following example that helps you to clarify the answer and verify the concept of this power to weight ratio calculator.

Example

Find the vehicle horsepower to weight ratio whose vehicle’s power is 550 hp and the vehicle weight is 15000 pounds.

Solution:

Vehicle power P = 550 hp

Vehicle weight W = 15000 pound

Power to weight ratio = P/W

= 550/15000

= 0.0366

With this horsepower to weight calculator, you can also attain your answer in other units, such as watt, kilowatt, horsepower, joule per second, and more.

FAQs:

What is a good power to weight ratio?

Power to weight ratio varies across a wide range spectrum. Generally, untrained riders have an FTP below 2.0 W/kg for men and 1.5 W/kg for women, whereas, professional racers may be capable of maintaining more than 6.0 W/kg for men and 5.5 for women.

Is it better to have a higher or lower power to weight ratio?

A higher power-to-weight ratio is better than having a lower power-to-weight ratio. Since the vehicles having higher PWR accelerates with the highest speed and the vehicles which are having the lowest PWR accelerate with lesser speed.

How to measure the performance of a car using PWR?

You have to provide engine power and vehicle weight in the mentioned input fields of the Power to Weight Ratio cars Calculator and click the calculate button to get the result easily.

What is the significance of the PWR ratio calculator?

The significance of the power to weight ratio calculator is that it can indicate the performance quite accurately and calculate the under special conditions in certain places.

Conclusion:

The power to weight ratio plays an important role in the mechanical fields. Although, you can measure the performance of how fast a vehicle can travel with our power to weight ratio calculator. If your car has a higher power-to-weight ratio, your car will go faster.
