How many Liters per 100 km is 1 Kilometers per gallon (US)?

1 Kilometers per gallon (US) = 378.5411784 Liters per 100 km. Multiply kilometers per gallon (us) by 378.5411784 to get liters per 100 km.

How many Kilometers per gallon (US) is 1 Liters per 100 km?

1 Liters per 100 km = 378.5411784 Kilometers per gallon (US). Divide liters per 100 km by 378.5411784 or multiply by 378.5411784.

What is the formula for Kilometers per gallon (US) to Liters per 100 km?

Liters per 100 km = Kilometers per gallon (US) × 378.5411784. All factors are from BIPM/NIST via OmniConverter's base-unit engine.

How do I convert L/100km to MPG?

Divide 235.21 by your L/100km value to get US MPG. For example, 8 L/100km = 29.4 MPG.

What is the difference between US MPG and UK MPG?

A US gallon (3.785 L) is smaller than a UK gallon (4.546 L), so UK MPG numbers are higher for the same vehicle.

How do I convert MPG to L/100km?

Divide 235.21 by your MPG value to get L/100km. For example, 30 MPG = 7.84 L/100km.

What is km/L and how does it relate to L/100km?

km/L measures how many kilometers you can travel per liter. Divide 100 by km/L to get L/100km.

Why do different countries use different fuel consumption units?

L/100km is used throughout Europe and Canada, MPG in the US and UK, and km/L in parts of Asia and Africa.

Is higher or lower L/100km better?

Lower L/100km is better, it means the vehicle uses less fuel to travel the same distance.

Is higher or lower MPG better?

Higher MPG is better, it means the vehicle travels further on the same amount of fuel.

What is the average fuel consumption for a car?

The average modern car consumes about 6-8 L/100km (30-40 MPG), depending on size and engine.

Can I convert fuel consumption for electric vehicles?

EV efficiency is usually measured in kWh/100km rather than fuel consumption, as EVs don't consume liquid fuel.

How accurate are the fuel consumption conversions?

Conversions use exact mathematical formulas based on the US gallon (3.785411784 L) and UK gallon (4.54609 L).

Conversion Formula

Liters per 100 km = Kilometers per gallon (US) × 378.5411784

Kilometers per gallon (US) = Liters per 100 km × 378.5411784

Factors are from BIPM SI brochure and NIST SP 811, stored unrounded and computed via a base unit. Reverse factor is 1 ÷ 378.5411784.

How to convert Kilometers per gallon (US) to Liters per 100 km

Multiply the value in kilometers per gallon (us) by 378.5411784 to get liters per 100 km. For example, 5 Kilometers per gallon (US) = 75.70823568 Liters per 100 km. All results in the fuel consumption converter update instantly as you type, so you can see every unit at once without manual math.

Common mistakes

Do not round the factor to 378. too early — keep full precision until the final display. For fuel consumption, always verify critical calculations (medicine, engineering) with a second source.
