40 Grams to ml

40 grams to ml is ingredient-specific. Water is simple: 40g = 40ml. Flour, sugar, rice, butter, and honey need density-based conversion.

40 Grams in ml by Ingredient

Ingredient	Milliliters	Density note
water	40 ml	1 ml water is 1 gram at kitchen precision.
whole milk	38.83 ml	Milk is slightly denser than water.
all-purpose flour	75.61 ml	Spoon & Level flour; scooping can be heavier.
granulated sugar	47.34 ml	Granulated sugar is much denser than flour.
butter	41.71 ml	Solid butter, before melting.
cooked white rice	59.88 ml	Fluffed cooked rice; packing changes the weight.
honey	28.17 ml	Honey is denser than water and milk.

40 grams of water is 40 ml at kitchen precision.

40 grams of all-purpose flour is about 75.61 ml using Spoon & Level density.

Grams are weight and milliliters are volume. A dense ingredient needs fewer milliliters for the same gram weight than a light ingredient.
