How Unit Conversion Works
📏 Length & Area
Length and area conversions use fixed ratios based on the meter and square meter as SI base units. 1 inch = 2.54 cm exactly; 1 acre = 4046.86 m²; 1 bigha ≈ 2529 m² (North India).
⚖️ Weight
Weight conversions use the gram as the SI base unit. 1 pound = 453.59 g; 1 stone = 14 lb = 6350 g; 1 kilogram = 2.20462 lbs.
🌡️ Temperature
Temperature uses offset formulas: °F = (°C × 9/5) + 32; K = °C + 273.15. These are the only non-linear conversions on this page.
⛽ Fuel Economy
MPG and L/100km are inversely related: L/100km = 235.215 ÷ mpg. 1 US mpg = 0.425 km/L. India uses km/L (kpl); Europe uses L/100km.
