What is this?

A unit converter helps you translate measurements between different unit systems (metric vs imperial, or within the same system). Common conversions include length (inches to centimeters), weight (pounds to kilograms), temperature (Fahrenheit to Celsius), and more. Understanding unit conversions is essential for international travel, cooking, construction, science, and everyday problem-solving.

How to use

Select the conversion category (length, weight, temperature, etc.), enter the value you want to convert, select the unit you're converting from, and view all equivalent values in different units.

Tips

  • **Quick length:** 1 inch = 2.54 cm, 1 foot = 30.48 cm, 1 mile = 1.61 km
  • **Quick weight:** 1 pound = 0.45 kg, 1 ounce = 28.35 grams
  • **Quick temperature:** Celsius = (Fahrenheit - 32) × 5/9
  • **Cooking conversions:** 1 cup = 236 ml, 1 tablespoon = 15 ml, 1 teaspoon = 5 ml
  • **Memorize one:** Learn just one conversion factor per category (e.g., 1 inch = 2.54 cm) and calculate the rest
  • **Rounding matters:** For most practical purposes, 1 kg ≈ 2.2 lbs and 1 mile ≈ 1.6 km is accurate enough
