How It Works
Formula
Variables, symbols and units
- Input value
- Converted weight
- Conversion factor of the source unit (grams per unit)(g)
- Conversion factor of the target unit (grams per unit)(g)
Calculation method explained
The calculator converts your value into grams as a base unit, then converts from grams into the target unit. That gives stable weight and mass conversions across metric and imperial pairs.
Reference factors used by the calculator (grams per unit):
- 1 mg = 0.001 g
- 1 g = 1 g
- 1 kg = 1000 g
- 1 oz = 28.349523125 g
- 1 lb = 453.59237 g (16 oz)
The value is first multiplied by the source factor to get grams, then divided by the target factor to land in the chosen unit.
