Mass and everyday weight units
Kilograms, grams, pounds and ounces are commonly converted as mass units in everyday use. In physics, mass and force are different quantities, so engineering work involving force should use the appropriate force units rather than treating them as interchangeable.
Rounding converted weights
A conversion can produce more decimal places than the original measurement justifies. Preserve useful precision for calculations, but avoid implying greater measurement accuracy than the source value provides.
