How do I convert between metric and imperial units?
Our unit converter makes it easy to convert between metric units (meters, kilograms, liters) and imperial units (feet, pounds, gallons). Simply select the category (length, weight, volume, etc.), choose your "from" unit (e.g., meters), choose your "to" unit (e.g., feet), enter the value, and click convert. The calculator handles all conversion factors automatically, so you get accurate results instantly.
How accurate are the unit conversions?
Our unit converter uses standard conversion factors recognized internationally. Conversions are highly accurate for most practical purposes. For example, 1 meter = 3.28084 feet, 1 kilogram = 2.20462 pounds, and 1 liter = 0.264172 gallons. The calculator displays results with appropriate precision based on the units being converted. For scientific or engineering applications requiring extreme precision, verify conversion factors for your specific use case.
Can I convert temperature between Celsius, Fahrenheit, and Kelvin?
Yes, our unit converter includes temperature conversion between Celsius (°C), Fahrenheit (°F), and Kelvin (K). Select the temperature category, choose your "from" and "to" units, enter the temperature value, and convert. The calculator uses standard formulas: Fahrenheit = (Celsius × 9/5) + 32, Kelvin = Celsius + 273.15. This is useful for weather, cooking, scientific calculations, and international travel.
