The weight of a car is typically measured in pounds (lbs) in the United States or in kilograms (kg) in most other countries. For example, a standard passenger car may weigh between 2,000 to 4,000 pounds or approximately 900 to 1,800 kilograms. When discussing vehicle specifications, manufacturers often provide the weight in both units for broader understanding.
You would use the unit of measurement called "kilograms" or "pounds" to measure the weight of a car.

It is customary to use the kilogram - though that is technically not a weight, but a mass.

In SI (International System of Units) - kilograms/tons (ton = 1000 kg), in American system - pounds.
You would use the metric unit "kilograms" to measure the weight of a bag of groceries.

Pound weight.
I personally use the pound avoirdupois.
