Why do I need to convert between mile/gallon (US) and mile/gallon (UK)?

Because the US and UK use different gallon definitions, converting ensures accurate comparison of fuel economy ratings across these regions.

Can this tool convert fuel economy to liters per 100 kilometers?

No, this tool specifically converts between mile per gallon (US) and mile per gallon (UK) units; however, mile/gallon (UK) values can be converted to L/100 km separately.

Does the conversion affect vehicle emissions or real-world fuel consumption?

No, the conversion only changes the units and does not consider fuel composition or driving conditions that affect actual emissions or fuel usage.
