Brix (°Bx) Formula (by Mass)

The following formula is used to calculate degrees Brix (°Bx) from masses. °Bx is a concentration (mass percent of sucrose), not a density.

^{\circ}\!Bx = \frac{Su}{So}\times 100
  • Where °Bx is degrees Brix, equal to the mass percent of sucrose: grams of sucrose per 100 g of solution (w/w).
  • Su is the mass of sucrose (any mass unit).
  • So is the total mass of solution (same mass unit as Su).

To calculate °Bx by mass, divide the mass of sucrose by the total mass of solution, then multiply by 100 (equivalently, divide by So/100).

How to Calculate °Brix (by Mass)?

The following example problems outline how to calculate °Brix (°Bx).

Example Problem #1:

  1. First, determine the mass of sucrose.
    1. The mass of sucrose is given as: 12 g.
  2. Next, determine the total mass of solution.
    1. The mass of solution is provided as: 600 g.
  3. Finally, calculate °Brix using the equation above: 

°Bx = Su / (So/100)

The values given above are inserted into the equation below:

°Bx = 12 / (600/100) = 2 °Bx (≈ 2% w/w sucrose)

Example Problem #2: 

For this problem, the variables needed are provided below:

mass of sucrose (g) = 12

mass of solution (g) = 50

This example problem is a test of your knowledge on the subject. Use the calculator above to check your answer.
