How to Use the Unit Converter
Getting Started
- Step 1: Select the measurement category (length, weight, temperature, etc.)
- Step 2: Enter the value you want to convert
- Step 3: Choose the source unit and target unit
- Step 4: Click "Convert" to see the result with formula
Supported Categories
- Length: Metric (mm, cm, m, km) and Imperial (in, ft, yd, mi) units
- Weight & Mass: Grams, kilograms, pounds, ounces, tons, and more
- Temperature: Celsius, Fahrenheit, Kelvin, and Rankine
- Volume: Liters, gallons, cups, quarts, and cubic measurements
- Area: Square units from millimeters to kilometers and miles
Best Practices
- Precision: Results show up to 6 decimal places for accuracy
- Verification: Double-check important conversions with official sources
- Context: Consider the appropriate precision for your specific use case
- Units: Always specify units clearly when communicating measurements
Common Applications
- International Trade: Convert between metric and imperial systems
- Cooking & Recipes: Convert measurements for different serving sizes

- Science & Engineering: Precise unit conversions for calculations
Frequently Asked Questions
Why are there slight differences compared to other converters?
Small differences can occur due to rounding methods and the precision of conversion factors used. Our converter uses internationally accepted conversion factors and displays results to 6 decimal places for maximum accuracy.
What's the difference between weight and mass?
Mass is the amount of matter in an object (measured in kg), while weight is the force of gravity on that mass (measured in Newtons). In everyday use, we often use "weight" when we mean "mass," and our converter follows this common usage.
How accurate are temperature conversions?
Temperature conversions are mathematically exact using the standard formulas. Celsius to Fahrenheit: °F = °C × 9/5 + 32. Kelvin conversions add or subtract 273.15 from Celsius values.
Can I convert between different types of measurements?
No, you can only convert within the same measurement category. For example, you cannot directly convert length to weight. Each category has its own base units and conversion factors.
Why does the converter show so many decimal places?
High precision is important for scientific and engineering applications. You can round the result to the appropriate number of significant figures for your specific use case.
Are imperial and US customary units the same?
Mostly yes, but there are some differences, particularly in volume measurements. For example, US and UK gallons are different sizes. Our converter specifies which system is being used when there are differences.
