Fluid ounce versus ounce of mass
People say ounce for both. A fluid ounce is volume. An avoirdupois ounce is mass. Water near 4 °C is about 1 g/ml, so 1 US fl oz of water is near 29.57 g, which is not 1 avoirdupois ounce. Medicine cups and bottles use milliliters. This list uses the US fluid ounce, not the imperial fluid ounce.
When to convert milliliters to fluid ounces here
Read a 500 ml bottle as US fl oz, check a 8 fl oz glass as milliliters, or move to cups. Keep recipe-only spoons on cooking if you want the shorter list.
