Understanding Different Weight Units
Different countries and industries use various weight measurement systems:
Metric System Units
- Kilograms (kg): The base unit of mass in the metric system, used worldwide for most measurements
- Grams (g): Commonly used for smaller measurements, especially in cooking (1000g = 1kg)
- Milligrams (mg): Used for very small measurements like medication doses (1000mg = 1g)
- Micrograms (µg): Used in scientific measurements (1,000,000µg = 1g)
Imperial/US Customary Units
- Pounds (lb): Commonly used in the United States for body weight and goods
- Ounces (oz): Used for smaller measurements, especially in cooking (16oz = 1lb)
- Stones (st): Primarily used in the UK and Ireland for body weight (1st = 14lb)
- Tons: Used for heavy measurements (US ton = 2000lb, metric tonne = 1000kg)
Did You Know? The kilogram is the only SI base unit with a prefix as part of its name. It’s also the only one still defined by a physical artifact (the International Prototype Kilogram) rather than a fundamental physical property.
