# Often asked: How To Calculate Power To Weight Ratio Motorcycle?

## What is a decent power to weight ratio?

This means you can generate 4.05 watts for every kilogram of body weight. A power to weight ratio of 4 to 4.5 is equivalent to a competitive Category 2 racer. A power to weight ratio of 5-6 would put you in the range of a Category 1 elite professional (according to Andy Coggan’s power profiling chart).

## How do you calculate torque to weight ratio?

if a pointer is having less weight, it will be having high torque / weight ratio so that even for a very small deflection pointer starts moving and indicates measured value. You just need to remember three simple statement:

1. Energy is always conserved.
2. Power is rate of consuming energy.
3. Power = Torque * Angular Speed.

## How do you calculate kw per tonne?

To figure out your kw / tonne, You divide your MAX ” kw ” performance as specified by the manufacturer by your vehicles curb weight. You then multiply by 1000.

## What does power to weight ratio indicate?

A “ Power to Weight Ratio ” is the term used to describe the relationship between a measurement of power [usually Kilowatt units] and its ability to move and accelerate a vehicle of a particular weight. Put simply, it is a way of describing the ability of the engine’s power to move the ‘ weight ‘ of the vehicle.

## Is 200 watts good cycling?

Most pro cyclists produce about 200 to 300 watts on average during a four-hour tour stage. The recreational rider, on the other hand, might be only able to sustain this wattage during a 45-minute or hour-long spin class. “That’s what’s great about wattage.

## Is 4 watts per kg good?

So it is that many club level cyclists have the goal of being able to achieve a functional threshold power (FTP) of 4W/ kg. However, 4W/ kg is still better than most club level cyclists, and is literally lapping everyone on the couch. So it’s a great goal to target.

## What is torque to weight ratio?

Definition: The ratio of torque to the weight of the moving part of an instrument is known as a torque / weight ratio. It indexes the performance of the instrument. The high value of the torque – weight ratio shows that even for the small value of deflecting torque, the pointer deflects and shows the measured value.

## Which instrument has highest torque to weight?

The permanent magnet moving coil instrument (PMMC) has the highest torque/weight ratio.

## How do you calculate power to weight?

It’s very easy to calculate a power-to-weight ratio. Simply divide the power output of a vehicle by its weight. For example, if you have a car that weights 2000 pounds and has 250 hp, the PWR will be as follows: 250 / 2000 = 0.125 hp for every pound of car.

## How do you calculate watts per kg?

Watts per Kilo is your max power output, in watts, divided by your weight in kilos. For example, someone with a weight or mass of 80kg with a sustainable power output of 280 watts will have a power to weight ratio of 3.5 watts per kilo (3.5W/ kg ).

## How do I calculate power?

Power is a measure of the amount of work that can be done in a given amount of time. Power equals work (J) divided by time (s). The SI unit for power is the watt (W), which equals 1 joule of work per second (J/s). Power may be measured in a unit called the horsepower.

## What car has the best power to weight?

Top 50 Supercars listed by power to weight ratios

No. Make Power to Weight (hp/lb)
1 Hennessey 55.87
2 McLaren 51.97
3 McLaren 51.74
4 SSC 51.92

## Is power to weight ratio important?

In simple terms, your power to weight ratio is simply the amount of power you can output per kilogram of weight. Once you’ve worked out your power to weight ratio however, you can start to optimise it and improve your performance.

## What is the benefit of more power to weight ratio?

But in terms of sheer acceleration ability and speed – the higher your power to weight ratio, the better. That means the ideal performance car is lighter in curb weight but jacked to the hilt in horsepower.

## What are the benefits of better power to weight ratio?

Since the engine has less to haul, it can focus more on speeding up. The same principle applies to athletes. By cutting on down the amount of weight they’re carrying, an athlete can increase his or her speed and endurance. The more power an athlete has per pound, the higher the power-to-weight ratio.
