Conversion formula
Linear unit conversions use standardized factors; many are exact by definition (e.g., 1 in = 25.4 mm, 1 ft = 0.3048 m).
Common mistakes
- Confusing mass (lb) with force (lbf) in engineering contexts.
- Mixing metric tonnes (t) with short/long tons.
Unit facts
- Tonne (t): A metric tonne is exactly 1,000 kg; standard for freight and industrial production.
- Milligram (mg): A milligram is 1/1,000,000 of a kilogram; used in pharma and lab work.
About Mass
Mass quantifies the amount of matter. The kilogram is defined by Planck’s constant, which anchors mass to fundamental physics. In practice, grams and pounds dominate everyday use—from recipes and parcels to body weight—while tonnes and long tons appear in logistics and industry.
About Tonne (t)
Tonne (t)
Metric ton equals 1,000 kg. Used in logistics, emissions reporting (CO₂e), and industrial output. Works well with SI prefixes (kt, Mt).
History: Adopted with the metric system to simplify bulk trade; not to be confused with short ton (US) or long ton (UK).
About Milligram (mg)
Milligram (mg)
Equals 1/1,000,000 kg. Used for dosages, trace contaminants, gemstones, and fine powders. Requires calibrated balances for accuracy.
History: Common in analytical chemistry and pharmacology as instrumentation reached sub-milligram readability.
