Have you ever thought about the density of plywood? But, today you have a chance to learn all about plywood density. Why have we chosen this topic? Can you guess? Let us tell you, plywood is now playing an important role in partitions, floors, ceilings, and sheathing. It is also used for decorative purposes both in exterior positions, such as cladding and doors, and internally as cabinets, shelves, and furniture. In these uses, the density of plywood plays a crucial role. For instance, if you want to make a ceiling of plywood then first you need to check the capacity of the walls to bear the weight of plywood, otherwise, it may fall down. Let’s have a look at the density of plywood.

**What Is The Density Of Plywood? **

The density of plywood is in the range of 500 to 650 kg/m3. The plywood density can be changed according to the types of wood the manufacturers are using. Therefore, we have mentioned a range and not a specific value. You can buy plywood as per your choice. But, there are such plywoods in the market whose density exceeds this range like the density of Eucalyptus hardwood plywood is more than 900 km/m3. Therefore, you can say that plywood density can not be fixed and it depends on the timber species used.

Plywood density can be expressed in different units as,

- The density of plywood lb/in3 is between 25 and 50 lb/in3
- The density of plywood in g/cm3 is 0.3 to 0.5 g/cm3
- The density of plywood kg/m3 is between 500 and 650 kg/m3
- The density of plywood in lb/ft3 is s between 25 and 50 lb/ft3
- The poplar plywood density is 400 kg/m3
- The density of plywood 18 mm is between 672 and 700 kg/m3

Now, you know the density of plywood g/cm3. Let’s understand the definition of the density of plywood in detail.

**Definition Of Density Of Plywood **

The density of plywood is defined as the amount of plywood that can be compatible with one comic area called its density. Or, the ratio of the mass and volume of the plywood. Plywood density is directly proportional to the mass of plywood and inversely proportional to the volume of plywood. This means, as mass increases, the density alo increases and vice versa. While, as the volume of plywood increases the density of plywood decreases and vice versa. The definition of plywood is can be expressed in the equation form as,

The density of Plywood = mass of Plywoodvolume of Plywood g/cm3

In the symbolic form,

D = mv g/cm3

Where, d – the Plywood density,

v – the volume of Plywood, and

m – the mass of Plywood

Let’s know how to find the density of plywood.

**How To Calculate Density Of Plywood? **

The Calculation of plywood density is very easy. For that, you only need to know two variables namely, the mass and volume of plywood. To measure the mass of selected plywood you need to just weigh it by using a balance. And to measure its volume you can use a mathematical formula. For instance, if you want to measure the density of rectangular plywood with a length of 10 m, height of 2 m, and breadth of 8 m, then its volume would be 10 x 2 x 8 = 160 m3.

Let’s understand it by taking an example.

Squircle plywood with a weight of 3200 kg. The length of the side of the plywood is 2 m, what will be its density?

To calculate the density, we need the volume of plywood. Here the plywood is of square shape so, the volume of plywood would be = 2 x 2 x 2 = 8 m3

now, by considering the formula of density,

The density of Plywood = mass of Plywoodvolume of Plywood

= 3200/8

= 400 kg/m3

**FAQ**

**How Much Does A 4×8 Sheet Of 5 8 Plywood Weigh?**

A: Each sheet of plywood weighs about 71 pounds, so 22 sheets would weigh about 1,562 pounds. Helpful?

**How Do You Calculate Density Of Plywood?**

Divide the weight by the volume to calculate specific weight, or Imperial density. In the example, if the weight was 20 pounds, then the density would be 20.4 pounds per cubic feet.

**How Much Does A 4×8 Sheet Of 7/16 Plywood Weigh?**

The 7/16″ 4×8′ OSB panel has a weight of 43.8 pounds.

**How Much Does A 4×8 Sheet Of 1/2 Inch Drywall Weigh?**

A conventional 1/2-inch sheet of drywall measuring 4 feet by 8 feet weighs just over 51 pounds

**How Heavy Is 8×4 Plywood?**

Stacks of 4′ x 8′ softwood plywood panels, 15/32-inch thick. Each sheet weighs **about 40 pounds**, so each one of those stacks weighs almost a ton and a half.

**Conclusion **

Plywood is majorly needed where one requires higher quality, high-strength sheet material. It must be braking, bending, cracking, warping, and twisting. Exterior glued plywood is good for outdoor use, but optimal performance happens when the moisture content is low. Subzero conditions don’t affect the dimensional or strength properties of plywood so good for certain applications. It has done well for aviation purposes and the shipping industry since World War 2. Plywood has inherently good strength properties that can be engineered for certain uses. This was all about the density of plywood.
