Vehicle Weight Converter - kg to lbs, Tons and Back

A 3,500 lb SUV in Detroit is a 1,588 kg family car in Berlin

Same sheet metal, same engine, completely different numbers on the spec sheet. American car listings quote curb weight in pounds (lb). European documents use kilograms (kg). Trucking regulations throw in metric tons, US short tons and UK long tons - three units that all sound like "tons" but differ by up to 12%. This converter handles all five weight units in every direction, with the conversion factors built in.

How to convert vehicle weight - step by step

Enter the weight - type the value from your spec sheet, registration document or listing. Decimals work (e.g. 1.5 for 1.5 metric tons).
Select the source unit - kg, pounds, metric tons, US short tons or UK long tons.
Select the target unit - pick the unit you need for your form, comparison or calculation.
Read the result - the converter shows the exact value, formula and practical context for the weight range.

Vehicle weight reference table

Curb weight (kerb weight) is the vehicle ready to drive with all fluids, without passengers or cargo. GVW (Gross Vehicle Weight) is the maximum loaded weight.

Vehicle type	Curb weight (kg)	Curb weight (lb)	Examples
City car	900-1,100	1,984-2,425	Fiat 500, VW Up, Toyota Aygo
Compact	1,100-1,400	2,425-3,086	VW Golf, Honda Civic, Mazda 3
Sedan / wagon	1,400-1,800	3,086-3,968	BMW 3 Series, Toyota Camry, Audi A4
SUV / crossover	1,500-2,500	3,307-5,512	RAV4, X5, Tahoe, Range Rover
Pickup truck	2,000-3,000	4,409-6,614	Ford F-150, RAM 1500, Toyota Tundra
Electric car	1,600-2,700	3,527-5,952	Tesla Model 3 (1,760 kg), Model X (2,460 kg)

Three types of ton - a comparison

Type	In kg	In lb	Where used
Metric ton (t)	1,000	2,204.62	Worldwide (EU, Asia, most of the world)
US short ton	907.185	2,000	United States (trucking, industry)

Fun facts about vehicle weight

Battery weight: The battery pack of a Tesla Model S weighs about 544 kg (1,200 lb) alone - more than an entire Lotus Elise (920 kg). Electric cars are consistently 300-500 kg heavier than their combustion equivalents.

Heaviest production car: The GMC Hummer EV tips the scales at 4,103 kg (9,046 lb) - heavier than many commercial trucks. It needs special parking structures rated for its weight.

Lightest production car: The Caterham Seven 160 weighs just 490 kg (1,080 lb). That is less than a grand piano. Power-to-weight ratio beats most supercars.

Weight creep: The original 1974 VW Golf weighed 790 kg. The current Golf 8 weighs 1,310 kg - a 66% increase in five decades. Safety equipment, sound insulation and electronics add up.

Practical examples

Car import from the US: A listing says curb weight 3,649 lb. What is that in kg?
Result: 3,649 x 0.454 = 1,656 kg - a mid-size sedan, well under the 3,500 kg Class B license limit.

Bridge weight limit: A rural bridge in the UK has a 7.5 long ton limit. Your loaded van weighs 6,800 kg. Can you cross?
Limit: 7.5 x 1,016 = 7,620 kg. Your van (6,800 kg) clears it with 820 kg to spare.

Towing capacity: Your truck can tow 5,000 lb. A European trailer weighs 1,800 kg. Safe?
Trailer: 1,800 x 2.205 = 3,969 lb. Tow limit: 5,000 lb. Yes, with 1,031 lb margin.

Truck regulation: A shipping document says 22 short tons. How many metric tons?
Result: 22 x 907.185 = 19,958 kg = 19.96 metric tons. Just under the 20 t axle limit.

EV comparison: A Tesla Model 3 Long Range weighs 1,830 kg. An equivalent BMW 330i weighs 1,530 kg. Difference?
Delta: 300 kg (661 lb) - almost entirely the battery pack weight.

FAQ - Frequently asked questions

What is the difference between curb weight and gross vehicle weight?

Curb weight (kerb weight in British English) is the vehicle empty but ready to drive - with all fluids (fuel, oil, coolant) but without passengers or cargo. Gross Vehicle Weight (GVW) or GVWR is the maximum allowed total weight including the vehicle, passengers, cargo and accessories. The difference is your available payload capacity. Example: a car with 1,500 kg curb weight and 2,100 kg GVWR has 600 kg of payload capacity.

Why do American cars seem so much heavier?

Two reasons. First, the numbers look bigger because pounds are smaller than kilograms - a 1,500 kg car is 3,307 lb. Second, American market preferences genuinely favor larger vehicles. The average new car sold in the US in 2024 weighed about 1,860 kg (4,100 lb), compared to 1,400 kg (3,086 lb) in Europe. Pickup trucks and full-size SUVs dominate US sales but are rare in Europe.

How do I quickly estimate kg to pounds in my head?

Multiply by 2 and add 10%. Example: 1,500 kg x 2 = 3,000, plus 10% (300) = 3,300 lb. Actual: 3,307 lb. Error: under 0.3%. For the reverse (lb to kg), divide by 2 and subtract 10%. Example: 4,000 lb / 2 = 2,000, minus 10% (200) = 1,800 kg. Actual: 1,814 kg.

Does vehicle weight affect fuel consumption?

Significantly. As a rule of thumb, every 100 kg (220 lb) of extra weight increases fuel consumption by about 0.3-0.5 L/100km (roughly 1-2% for a mid-size car). This is why manufacturers chase weight reduction - replacing steel with aluminum saves weight and fuel. A 300 kg lighter car saves roughly 1-1.5 L/100km over its lifetime.

What weight limit applies to a Class B driving license?

In most European countries, a standard (Class B) license allows driving vehicles up to 3,500 kg GVW (Gross Vehicle Weight). This means the total loaded weight of the vehicle - not just the curb weight. Large vans, motorhomes and some electric vehicles with heavy batteries can exceed this limit. In the US, a standard license typically covers vehicles up to 26,000 lb (11,793 kg) GVWR - much more generous than Europe.

When would I need to use short tons or long tons?

US short tons (2,000 lb) appear in American trucking regulations, freight shipping quotes and industrial materials. If a US supplier quotes "10 tons of gravel," they mean 9,072 kg, not 10,000 kg. UK long tons (2,240 lb) are mostly historical but still appear in British shipping and older engineering documents. When in doubt, ask which ton is meant - the 12% difference between a short ton and a metric ton can matter.
