Sugar Weight Calculator

Work out sugar weight instantly with clear inputs, formula shown and shareable results.

About Sugar Weight Calculator

Cup weight depends on crystal size and packing: granulated is about 200 g a cup, packed brown 220 g, and icing sugar only 120 g because it is mostly air. Swapping icing sugar for granulated cup for cup nearly halves the sugar by weight, which changes both sweetness and structure in a bake.

Formulas

Weight

grams = cups x grams per cup for that sugar type

Energy

kcal = grams x 3.87, the accepted energy density of sucrose

Worked example

With the default values below, Sugar Weight Calculator returns Weight of sugar of 300.0. Change any input above and every figure here is recalculated in your browser.

Assumptions and limits

  • The result is derived only from the 2 inputs listed above. Anything not among them is not part of the calculation.
  • In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
  • Figures are rounded for display to 2 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

How is the Sugar Weight figure worked out?

grams = cups x grams per cup for that sugar type. Cup weight depends on crystal size and packing: granulated is about 200 g a cup, packed brown 220 g, and icing sugar only 120 g because it is mostly air.

Why does this matter?

Swapping icing sugar for granulated cup for cup nearly halves the sugar by weight, which changes both sweetness and structure in a bake.

What do I need to enter?

Enter cups of sugar, sugar type. The defaults shown are a realistic worked example — swap in your own figures to get a result you can use.
