Length Conversions
The metric system (SI) is based on the meter, with prefixes indicating powers of 10: kilometer (km), centimeter (cm), millimeter (mm). The imperial system uses inches, feet, yards, and miles. Key conversions: 1 inch = 2.54 cm, 1 foot = 30.48 cm, 1 mile = 1.609 km, 1 yard = 0.914 meters.
Weight Conversions
The SI unit for weight/mass is the kilogram. The imperial system uses pounds and ounces. Key conversions: 1 kg = 2.205 lbs, 1 lb = 453.6 grams, 1 oz = 28.35 grams. Note: on Earth, mass and weight are proportional, so the same numbers work for everyday purposes.
Temperature Conversions
Three temperature scales are in common use: Fahrenheit (used in the US), Celsius (used in most countries), and Kelvin (used in science). Key conversions: 0°C = 32°F (freezing point of water), 100°C = 212°F (boiling point of water), 0K = -273.15°C (absolute zero).
