How to Convert Between Metric and Imperial Weight Units

Weight and mass are essential concepts in science, health, cooking, and daily life. Our Weight Converter helps you easily convert between metric units (milligrams, grams, kilograms, metric tons) and imperial units (ounces, pounds, stones, US tons, UK tons). Whether you're a student, chef, scientist, or traveler, understanding weight conversion is crucial for recipes, science experiments, fitness, and more. This tool provides instant, accurate results and educational explanations for each unit.

How to Use the Weight Converter

  • Enter the weight or mass value you want to convert.
  • Select the unit of the value (e.g., kilograms, pounds, ounces).
  • Click Convert to see the equivalent values in all supported units.
  • Use the results for science experiments, cooking, fitness tracking, or international travel.

Parameters Explained

  • Weight/Mass Value: The numeric value you want to convert. This can be any real number, positive or negative, and may include decimals for precision.
  • Unit: The scale of your input value. Choose from:
    • Milligrams (mg): Used for very small weights, especially in science and medicine. 1 mg = 0.001 g.
    • Grams (g): Common in science, cooking, and everyday use. 1 g = 0.001 kg.
    • Kilograms (kg): The base unit of mass in the metric system. 1 kg = 1,000 g.
    • Metric Tons (t): Used for large weights, such as vehicles or cargo. 1 t = 1,000 kg.
    • Ounces (oz): Used in the US for small weights, especially in cooking. 1 oz = 28.3495 g.
    • Pounds (lb): Common in the US and UK for body weight and groceries. 1 lb = 16 oz.
    • Stones (st): Used in the UK for body weight. 1 st = 14 lb.
    • US Tons (short ton): Used in the US for large weights. 1 US ton = 2,000 lb.
    • UK Tons (long ton): Used in the UK for large weights. 1 UK ton = 2,240 lb.

FAQs

  • Why are there different weight units?
