The factor
One gram is 1,000 mg. It is a simple decimal shift, but worth checking when reading supplement labels or spice doses.
Where it appears in cooking
- Vitamin and supplement labels (500 mg = 0.5 g)
- Precise spice dosing in professional recipes
- Caffeine content: 80 mg in an espresso
- Salt: 1 tsp fine salt ≈ 6,000 mg
Scale accuracy
Most kitchen scales resolve to 1 g — a 500 mg measurement is below their resolution. For sub-gram precision you need a jeweller's or coffee scale (0.1 g).
Conversion direction
Moving from mg to g divides by 1,000; the reverse multiplies. There is no rounding subtlety, which makes this the easiest conversion in the kitchen.
