Understanding Kilograms and Grams
The Kilogram (kg)
The kilogram is the base unit of mass in the International System of Units (SI). It's used worldwide for measuring body weight, food portions, and most everyday weights.
One kilogram is defined by the International Prototype Kilogram, a platinum-iridium cylinder kept in France. It's the only SI base unit still defined by a physical object.
Common uses for kilograms:
- Body weight (e.g., 70 kg adult)
- Luggage weight limits
- Large food packages
- Exercise equipment weights
The Gram (g)
The gram is a smaller metric unit, equal to 1/1000 of a kilogram. It's perfect for measuring ingredients, small portions, and precise quantities in cooking and science.
The gram is the most practical unit for cooking and baking, where precision matters. Most recipes specify ingredient amounts in grams for accuracy.
Common uses for grams:
- Recipe ingredients (e.g., 250g flour)
- Nutritional information
- Jewelry and precious metals
- Medicine dosages
