Convert 14 unit categories (length, weight, temperature, volume, cooking, area, speed, fuel economy, time, energy, pressure, angle, frequency, and data) instantly.
1 mile = 1.609 km · 1 inch = 2.54 cm · 1 foot = 30.48 cm · 1 yard = 0.9144 m · 1 nautical mile = 1.852 km.
Water freezes at 0°C (32°F, 273.15K) and boils at 100°C (212°F, 373.15K). Body temp is 37°C (98.6°F). Absolute zero is −273.15°C (0K).
1 pound = 0.4536 kg · 1 ounce = 28.35 g · 1 stone = 14 pounds · 1 metric ton = 2,204.6 lbs · 1 short ton (US) = 2,000 lbs.
1 US gallon = 3.785 L · 1 UK gallon = 4.546 L · 1 US cup = 236.6 mL · 1 metric cup = 250 mL · 1 US tbsp = 14.79 mL · 1 metric tbsp = 15 mL.
30 mpg (US) ≈ 7.84 L/100km · 1 mpg (US) = 1.201 mpg (UK) · L/100km = 235.21 ÷ mpg (US). Lower L/100km = better efficiency.
1 kcal = 4.184 kJ · 1 kWh = 3,412 BTU · 1 BTU = 1,055 J · Food calories (Cal) are actually kilocalories (kcal).
360° = 2π rad = 400 grad = 1 turn · 1 radian ≈ 57.296° · 1 Hz = 60 rpm · 1 GHz = 1,000 MHz.
1 byte = 8 bits · 1 KB = 1,024 bytes · 1 MB = 1,024 KB · 1 GB = 1,024 MB · 1 TB = 1,024 GB. Binary (base-2) system.
