📖 Measurement Guide
Everything you need to know about units and how to use Unit Converter Pro.
📐 Metric vs. Imperial Systems
The Metric System (SI) is used by most countries and is based on powers of 10. Examples: meter, kilogram, liter.
The Imperial System is primarily used in the United States. Examples: foot, pound, gallon.
Unit Converter Pro supports both systems, making it easy to convert between them.
🧠 How to Read Units
- km/h — Kilometers per hour (speed)
- m/s — Meters per second (speed)
- kg — Kilogram (weight)
- °C — Degrees Celsius (temperature)
- °F — Degrees Fahrenheit (temperature)
- L — Liter (volume)
- gal — Gallon (volume)
- Pa — Pascal (pressure)
📝 Common Conversion Formulas
Temperature:
°F = (°C × 9/5) + 32
°C = (°F − 32) × 5/9
K = °C + 273.15
°F = (°C × 9/5) + 32
°C = (°F − 32) × 5/9
K = °C + 273.15
