About Unit Conversion
Unit conversion is essential for international communication, science, trade, and everyday life. Most of the world uses the metric system, while the US primarily uses imperial units.
Metric vs Imperial
- Metric: Base-10 system, easy conversions (meter, kilogram, liter)
- Imperial: Traditional units (foot, pound, gallon)
- Only 3 countries don't officially use metric: US, Liberia, Myanmar
- Science universally uses metric (SI units)

Frequently Asked Questions
Why are there different unit systems?
Historical development in different regions. Metric was created in France during the French Revolution for standardization. Imperial evolved from English units.
Which system is better?
Metric is simpler (base-10) and used globally. Imperial has some practical advantages for everyday use (e.g., Fahrenheit for weather). Science uses metric universally.
How do I convert Celsius to Fahrenheit?
F = (C × 9/5) + 32. Or use the quick method: double it and add 30 for a rough estimate (e.g., 20°C ≈ 70°F).
What's the difference between weight and mass?
Mass is the amount of matter (kg). Weight is the force of gravity on that mass (Newtons). On Earth, we often use them interchangeably.
Why is 0°C = 32°F?
Fahrenheit was created before Celsius. 0°F was the coldest temp Fahrenheit could create (brine solution). Celsius later defined 0° as water's freezing point.
