Convert Kilometers per Liter to Miles per Gallon (US)

📜 Origins

Fuel efficiency became important during the 1970s oil crisis. The first MPG standards were set in 1975 with the CAFE regulations.

⚡ Historical Highlight

The Model T Ford got 21 MPG in 1908. Today's cars average 25 MPG - barely any improvement in 100+ years!

🎯 Fun Facts

• •One gallon of gasoline contains the energy equivalent of 500 hours of human labor!
• •The average car's fuel efficiency wastes about 80% of gasoline's energy as heat.
• •MPG (miles per gallon) in the US becomes L/100km elsewhere - showing fuel consumed per distance.

🏛️ Archaeological Discovery

Ancient Babylonians (2000 BCE) refined crude oil for waterproofing and lighting - humanity's first petroleum industry!

🚀 Modern Applications

Modern hybrid cars achieve over 50 MPG. Electric cars measure efficiency in MPGe (miles per gallon equivalent), using 33.7 kWh = 1 gallon.
