Litres Per 100km Formula:
| From: | To: |
The litres per 100km calculation is a standard metric for measuring vehicle fuel efficiency. It represents the amount of fuel (in litres) consumed to travel 100 kilometers, providing a clear measure of a vehicle's fuel economy.
The calculator uses the formula:
Where:
Explanation: This formula calculates fuel consumption per 100km by first determining the fuel consumption per kilometer and then scaling it up to 100 kilometers.
Details: Measuring fuel efficiency helps vehicle owners track fuel consumption patterns, compare vehicle performance, estimate fuel costs for trips, and identify potential mechanical issues that may affect fuel economy.
Tips: Enter the total fuel used in litres and the total distance driven in kilometers. For accurate results, measure fuel consumption over a significant distance (preferably a full tank) and ensure both values are positive numbers.
Q1: What is considered good fuel efficiency?
A: Good fuel efficiency varies by vehicle type. Generally, 5-8 L/100km is excellent for small cars, while larger vehicles may range from 8-12 L/100km.
Q2: How can I improve my vehicle's fuel efficiency?
A: Maintain proper tire pressure, avoid aggressive driving, reduce vehicle weight, perform regular maintenance, and use recommended fuel types.
Q3: How does this compare to miles per gallon (MPG)?
A: L/100km and MPG measure the same thing but inversely. Lower L/100km means better fuel efficiency, while higher MPG means better fuel efficiency.
Q4: Should I calculate over multiple fill-ups for accuracy?
A: Yes, calculating over several tanks provides a more accurate average as fuel consumption can vary based on driving conditions, traffic, and terrain.
Q5: Does fuel type affect consumption measurement?
A: Different fuel types (petrol, diesel, ethanol) have different energy densities, but the L/100km measurement remains valid for comparing consumption of the same fuel type.
