  • One teaspoon of water weighs about 4929 mg.
  • Water has a density of exactly 1 g/mL at 4 C; at room temperature it is 0.998 g/mL, so this is a close approximation.

Next stepRemember: the density of dried and ground ingredients can vary by how packed the container is. For critical applications like medication dosing, always use a calibrated scale.
