Frequently Asked Questions
How do I convert between metric and imperial units?
Select your starting unit (e.g., meters) and target unit (e.g., feet), then enter your value. The conversion happens automatically. For example, 1 meter = 3.28084 feet, 1 kilometer = 0.621371 miles, 1 kilogram = 2.20462 pounds. Our converter handles all metric-imperial conversions accurately using standard conversion factors.
What units can I convert with this tool?
Our converter supports 6 major categories: Length (meter, kilometer, mile, foot, inch, etc.), Weight (kilogram, pound, ounce, gram, etc.), Temperature (Celsius, Fahrenheit, Kelvin), Volume (liter, gallon, cup, milliliter, etc.), Area (square meter, acre, hectare, square foot, etc.), and Speed (km/h, mph, m/s, knot, etc.). Each category includes the most commonly used units.
How accurate are the unit conversions?
All conversions use internationally recognized conversion factors and are accurate to 6 decimal places. Temperature conversions use exact formulas: C = (F-32) × 5/9, F = C × 9/5 + 32, K = C + 273.15. Length, weight, and volume conversions use standard SI and USCS conversion ratios. Our tool is suitable for both everyday use and professional calculations.
Can I convert Celsius to Fahrenheit?
Yes! Select the Temperature category, enter your Celsius value, and choose Fahrenheit as the target unit. The formula is: °F = (°C × 9/5) + 32. For example: 0°C = 32°F (water freezes), 100°C = 212°F (water boils), 37°C = 98.6°F (normal body temperature). The conversion happens in real-time as you type.
What's the difference between metric and imperial systems?
The metric system (SI) uses base-10 units: meters for length, kilograms for weight, liters for volume. It's used worldwide and easy to convert (1 km = 1000 m). The imperial system uses feet, pounds, and gallons, primarily in the US. Imperial units don't follow a consistent pattern (1 mile = 5280 feet, 1 gallon = 128 ounces). Our converter handles both systems seamlessly, making it easy to switch between them.
