⚖️ Understanding Weight & Mass Units
Weight and mass measurements are used daily in cooking, shipping, fitness, science, and commerce. Different systems are used around the world:
- Kilogram (kg): Base SI unit of mass. 1 kg = 1000 grams. Used worldwide for everyday weights.
- Gram (g): 1/1000 of a kilogram. Used for small weights like food ingredients, jewelry, and medicine.
- Milligram (mg): 1/1000 of a gram. Used for very small quantities like medication dosages.
- Pound (lb): Imperial unit. 1 lb = 16 oz = 0.453592 kg. Used primarily in the US and UK.
- Ounce (oz): 1/16 of a pound = 28.3495 grams. Used for cooking, postal weights, and small items.
- Metric Ton (t): 1000 kg. Used for heavy weights like vehicles, shipping containers, and industrial materials.
