Tips & common mistakes

Quick tips

  • 1 kitchen tablespoon of water weighs about 15 g, but 1 tablespoon of flour is only 8 g — density varies.
  • A kitchen scale reads to 1 g; a jewellery scale to 0.01 g.
  • Gold is priced by gram in Europe and per troy ounce in international markets.

Avoid these

  • Assuming a tablespoon of any ingredient equals 15 g — true only for water.
  • Confusing g (gram) with mg (milligram) on medication labels.
  • Using 28 g instead of 28.35 g when converting an ounce in precision baking.
