Metric cups and other cup sizes
The figures above use the US customary cup of 236.6 ml. A metric cup is 250 ml, so a metric cup of baking soda weighs about 232 grams. UK recipes that say "cup" usually mean a 250 ml metric cup, which is why weighing in grams is more reliable than measuring by volume.
Measuring baking soda accurately
Stir baking soda briefly to break up any clumps before dipping your measuring spoon or cup into the box. Level it off with a flat edge without tapping or packing it down. Baking soda is used in small amounts, so weighing fractions of a gram improves leavening accuracy.
