The Wood Density Calculator finds the density of a wood sample by dividing its mass by its volume. Enter both measurements in compatible units to get a result you can use to compare samples or support material planning.

What Is Wood Density?

Wood density is the mass of wood per unit of volume. It is commonly expressed in kilograms per cubic meter (kg/m³) or grams per cubic centimeter (g/cm³). Density varies by wood species and can also be affected by moisture content and the sample itself.

Formula for Wood Density

$\text{Density} = \frac{\text{Mass}}{\text{Volume}}$

For example, when mass is measured in kilograms and volume in cubic meters, density is expressed in kg/m³.

How to Use the Wood Density Calculator

Enter the wood sample’s mass.
Enter its volume.
Make sure the units are compatible.
Read the calculated density.

Converting kg/m³ to g/cm³

To convert density from kilograms per cubic meter to grams per cubic centimeter, multiply by 0.001:

$\text{Density (g/cm}^3\text{)} = \text{Density (kg/m}^3\text{)} \times 0.001$

Example Calculation

Suppose a wood sample has a mass of 12 kg and a volume of 0.1 m³:

$\text{Density} = \frac{12}{0.1} = 120\text{ kg/m}^3$

Convert the result to g/cm³:

$120 \times 0.001 = 0.12\text{ g/cm}^3$

The sample density is 120 kg/m³, or 0.12 g/cm³. Be sure to use the actual sample volume; a volume of 100 m³ would produce a very different result.

FAQs

What units should I use for mass and volume?

Use compatible units. For example, mass in kilograms and volume in cubic meters gives density in kg/m³. Mass in grams and volume in cubic centimeters gives density in g/cm³.

Can this calculator estimate the density of any wood species?

Yes. It calculates density from the mass and volume you enter, regardless of species. The result applies to the measured sample and may vary with moisture content.

What is the density of pine wood?

Pine density varies by species, moisture, and condition. Use a measured sample for a more relevant estimate rather than relying on a single typical value.

Why did I get an unexpected density result?

Check that the mass and volume are for the same sample and that their units are compatible. Also verify the volume entry—for instance, cubic meters versus cubic centimeters can change the result substantially.

Does wood density indicate strength?

Density can help describe and compare wood, but it does not by itself establish strength or structural suitability. Species, grain, defects, moisture, and loading conditions also matter.
