Do not get stumped by metric units or weight measurements in the kitchen. Converting weight to volume can be done if you are familiar the substance you are converting, as ingredients have different densities. Mascarpone is a rich, buttery-flavoured cream cheese from Italy used in desserts like tiramisu. Density is the ratio of object's weight to its volume. Knowing the density of mascarpone will help you with conversion between different units of measurement.

Convert metric weight in grams to ounces. Divide the number of grams by 28.125, a conversion factor based on the density of mascarpone, to find the weight in ounces. For instance, if the weight of the cheese is 225 grams, the equation is: 225 / 28.125 = 227gr.

Multiply the number of ounces by 28.125 to find the weight of the cheese in grams. For instance, for 113gr of mascarpone: 4 x 28.125 = 112.5 grams.

Divide the number ounces by 8 to find the volume in cups of the mascarpone cheese. For instance, 454gr of mascarpone divided by 8 equals 2 cups of cheese.

Multiply the number of cups by 8 to find the number of ounces needed. For instance, if you need 1/2 cup of mascarpone cheese: 1/2 x 8 = 113gr.
