Moisture Content Calculator

Find moisture content from wet and dry mass.

Wet mass

Dry mass

Moisture (dry basis) (%) 20

Moisture (wet basis) (%) 16.667

Formula: dry basis = (wet − dry) ÷ dry × 100

Step-by-step with your numbers:

1. Values used:

2. Wet mass = 120

3. Dry mass = 100

5. Moisture (dry basis) = Wet mass - Dry mass = 120 - 100 = 20%

6. Moisture (wet basis) = 16.667%

Did we solve your problem today?

Moisture content measures how much water a sample holds, on a dry or wet basis.

The math behind it

Dry basis = (wet − dry) ÷ dry × 100. Wet basis divides by the wet mass instead.

120 g wet, 100 g dry → 20% dry basis (16.7% wet basis).

Which basis should I use?

Agriculture and wood often use dry basis; food often uses wet basis.
