Conversion Definitions
mpg
MPG stands for miles per gallon, measuring how many miles a vehicle can travel using one gallon of fuel. It is a common efficiency metric in countries using the imperial system, indicating fuel economy in terms of distance per volume.
liters
Liters are a metric unit of volume used to measure liquids, including fuel. One liter equals 1.000 liters, and it is used globally in fuel consumption metrics, representing the amount of fuel needed for a given distance or volume.
Conversion FAQs
How accurate is the 235.21 constant for mpg to liters conversion?
The constant 235.21 results from dividing 100 km by 1.60934 (mile to km conversion) and then dividing by 3.78541 (gallon to liters). It provides a precise way to convert miles per gallon to liters per 100 km, assuming standard unit conversions.
Why does the formula use 235.21 specifically?
The number 235.21 is derived from the calculation (100 / 1.60934) / 3.78541, which combines the conversions for distance and volume. It simplifies the conversion process by providing a direct formula between mpg and liters per 100 km.
Can I use this conversion for any mpg value?
Yes, the formula applies universally for any mpg value because it accounts for the units’ conversions. Just substitute the mpg value into the formula 235.21 / mpg to get liters per 100 km.
What should I do if my vehicle’s mpg is negative?
Negative mpg values are not physically meaningful, as fuel efficiency can’t be negative. If encountered, check the data source. For calculation purposes, only positive mpg values are valid for conversions.
