What is a Unit Converter?
A unit converter is an online tool that converts measurements between different units of the same quantity type. Whether you're converting between metric and imperial units, working with international measurements, following recipes from different countries, or completing school assignments, our unit converter handles length, weight, temperature, volume, area, speed, and more with instant, accurate results.
This converter supports conversions within and between measurement systems: metric (meters, kilograms, liters), imperial/US customary (feet, pounds, gallons), and specialized units. Select your measurement type, enter a value in any unit, and instantly see conversions to all related units. No manual calculation needed.
Why Use a Unit Converter?
Understanding measurements in different units is essential for international communication, travel, cooking, construction, science, and education. Americans traveling abroad encounter kilometers, kilograms, and Celsius temperatures. International recipes use grams and milliliters instead of cups and tablespoons. Manual unit conversion is tedious and error-prone, especially with complex conversion factors.
Students and educators use unit converters for science and math homework, learning conversion factors, and checking work. Professionals including engineers, architects, and scientists work with both metric and imperial units depending on project requirements and location. Cooks and bakers benefit from converting recipe measurements when using international cookbooks or scaling recipes.
The tool ensures accuracy using precise conversion factors, provides instant results across multiple units, and eliminates math errors from manual calculations. It's particularly valuable when traveling internationally, using foreign recipes, working on international projects, completing homework, or shopping online from international retailers.
Common Use Cases
International Travel: Convert temperatures (°F to °C), distances (miles to km), and speeds (mph to km/h) for navigation and understanding weather.
Cooking & Baking: Convert recipe measurements from metric to imperial or vice versa (grams to ounces, liters to cups, Celsius to Fahrenheit).
Construction & DIY: Convert between feet/inches and meters/centimeters when following international plans or buying materials from different regions.
Science & Education: Complete homework and lab assignments requiring unit conversions, learn conversion factors, and verify manual calculations.
Shopping: Convert clothing sizes, product weights, and dimensions when purchasing from international retailers or comparing products.
How to Use the Unit Converter
Using our unit converter is straightforward: select the measurement type (length, weight, temperature, etc.), enter your value in any supported unit, and instantly see conversions to all other units in that category. Common conversions include: 1 meter = 3.28 feet, 1 kilometer = 0.621 miles, 1 kilogram = 2.205 pounds, 1 liter = 0.264 gallons.
Temperature conversions use formulas: °F = (°C × 9/5) + 32, °C = (°F - 32) × 5/9, K = °C + 273.15. Common examples: 0°C = 32°F (freezing), 100°C = 212°F (boiling), 20°C = 68°F (room temp). Length: 1 inch = 2.54 cm, 1 foot = 30.48 cm, 1 mile = 1.609 km. Weight: 1 ounce = 28.35 grams, 1 pound = 453.6 grams, 1 ton = 907.2 kg. Volume: 1 cup = 236.6 ml, 1 gallon = 3.785 liters. All calculations are performed locally for instant results.
