Metric vs Imperial: Which Countries Use Which?
The metric system is the official measurement system in 195+ countries, including all of Europe, Asia, Africa, South America, and Australia. The SI (International System of Units) is the modern version of the metric system.
The United States is the main country using imperial/US customary units (pounds, miles, gallons, Fahrenheit) in everyday life. The UK uses a mix — official metric but still uses miles, pints, and stones informally.
Frequently Asked Questions
Common questions about metric to imperial conversion.
What is metric to imperial conversion?
Metric to imperial conversion is the process of translating measurements from the metric system (kilograms, meters, litres) used in most countries into the imperial/US customary system (pounds, feet, gallons) used primarily in the USA and, for some measurements, the UK.
How do I convert kilograms to pounds?
Multiply kilograms by 2.2046226218 to get pounds. Example: 70 kg × 2.2046 = 154.32 lbs. For a quick approximation, multiply by 2.2 and you'll be within 0.1% accuracy.
What is the metric system?
The metric system (officially the International System of Units, SI) is a decimal-based measurement system used globally for science and in everyday life in most countries. Its base units include: kilogram (mass), meter (length), second (time), and liter (volume).
Which countries use imperial measurements?
The United States is the primary country using the imperial/US customary system for everyday measurements. The UK uses a mix — metric officially, but imperial for road distances (miles) and beer (pints). Myanmar and Liberia also use some traditional systems.
How do I convert centimeters to inches?
Multiply centimeters by 0.393701 to get inches. Example: 30 cm × 0.393701 = 11.81 inches. Alternatively, divide centimeters by 2.54.
What is the formula for Celsius to Fahrenheit?
°F = (°C × 9/5) + 32. Example: 20°C → (20 × 9/5) + 32 = 36 + 32 = 68°F. Reverse: °C = (°F − 32) × 5/9.
How many liters in a gallon?
1 US gallon = 3.78541 liters. 1 UK (Imperial) gallon = 4.54609 liters. Note: US and UK gallons differ by about 20%.
