Mass / Weight Units
SI base unit of mass. Defined by the Planck constant. International standard for engineering mass measurements.
Common metric unit for small masses. Used in chemical dosing, material testing, and laboratory work.
Used for water quality measurements (mg/L), pharmaceutical dosing, and chemical analysis.
Used for trace contaminant concentrations (μg/L) in environmental engineering and water quality analysis.
Equal to 1000 kg. International standard for large masses in structural engineering, shipping, and construction.
Primary US customary mass unit. Exactly 0.45359237 kg. Used for material weights and structural loads.
Avoirdupois ounce, equal to 1/16 pound. Used for small material quantities and product specifications.
Used in water hardness measurement (grains per gallon), ballistics, and precious metals.
US customary unit of mass in the foot-pound-second system. Critical for dynamics: F = ma where F is in lbf and a is in ft/s².
