About Mass Calculation
Mass is a fundamental property of matter that measures the amount of substance in an object. Our calculator helps you convert between different units of mass and weight, calculate body mass index (BMI), and determine material density.
Measurement Units
Common units of mass and weight include:
- Metric System: Kilograms (kg), grams (g), milligrams (mg), metric tons (t)
- Imperial System: Pounds (lb), ounces (oz), stones (st), US tons (short ton), UK tons (long ton)
- Scientific: Atomic mass units (u), solar masses (M☉), Planck masses (mₚ)
Calculation Formulas
The formulas used in our calculator are:
- Unit Conversion: Uses precise conversion factors between units
- BMI: weight (kg) / [height (m)]²
- Density: mass / volume
Understanding BMI Categories
BMI is a screening tool for weight categories:
Underweight
BMI less than 18.5 may indicate undernutrition or other health issues.
Normal Weight
BMI between 18.5 and 24.9 is generally considered healthy.
Overweight/Obese
BMI of 25 or higher may indicate increased health risks.
