How do you measure mass of a car?

To measure the mass of a car, you can use a vehicle scale, which is a large platform that weighs the entire vehicle when it is driven onto it. Alternatively, you can use a set of portable scales placed under each wheel, which sum the weight of all four wheels to determine the total mass. For more precise measurements, the car should be on a level surface and have no additional weight (like passengers or cargo) at the time of measurement.
