Conversion Calculator
Convert between length, weight, volume, temperature, and area units. Supports metric and imperial systems with high precision.
How do I convert between different unit categories?
Select the conversion category (Length, Weight, Volume, Temperature, or Area), then choose the source and target units. Enter the value and click Calculate. The conversion calculator handles all the math using standard conversion factors. For example, to convert 10 feet to meters: select Length category, choose Feet as From and Meters as To, enter 10. The result is 3.048 meters using the factor 1 foot = 0.3048 meters.
What temperature conversions are supported?
The temperature category supports Celsius (°C), Fahrenheit (°F), and Kelvin (K). Celsius to Fahrenheit: °F = (°C × 9/5) + 32. Fahrenheit to Celsius: °C = (°F - 32) × 5/9. Celsius to Kelvin: K = °C + 273.15. Fahrenheit to Kelvin: K = (°F - 32) × 5/9 + 273.15. Common reference: 0°C = 32°F = 273.15K (water freezes), 100°C = 212°F = 373.15K (water boils).
What weight units can I convert between?
Weight conversions include kilograms (kg), pounds (lbs), ounces (oz), grams (g), milligrams (mg), and metric tons (t). Key conversion factors: 1 kg = 2.20462 lbs, 1 lb = 16 oz = 0.453592 kg, 1 oz = 28.3495 g, 1 metric ton = 1000 kg = 2204.62 lbs. For example, 5 kg = 11.02 lbs = 176.37 oz = 5000 g. The calculator provides precise conversions for cooking, shipping, fitness, and scientific applications.
How accurate are the area conversions?
Area conversions use exact mathematical conversion factors. Supported units: square meters (m²), square feet (ft²), square kilometers (km²), acres (ac), hectares (ha), and square miles (mi²). Key conversions: 1 m² = 10.7639 ft², 1 acre = 43,560 ft² = 4,046.86 m², 1 hectare = 10,000 m² = 2.47105 acres, 1 km² = 247.105 acres = 0.386102 mi². All results are accurate to 6 decimal places.
