How it works

Enter a value, select the source unit, and choose the target unit. Temperature conversions use affine formulas (°F = °C × 9/5 + 32); all others are multiplicative ratios. Be careful with US vs. UK fluid ounces and tons (short ton = 2,000 lb; metric tonne = 2,204 lb; long ton = 2,240 lb). Nutritional Calories (kcal) differ from physics calories by a factor of 1,000.
