Durometer to Young’s Modulus Calculator
Example 1: Converting Shore A Hardness to Young’s Modulus for an Elastomer
Given:
- Shore A Hardness = 70
To calculate Young’s Modulus (MPa), we use the formula:
Young’s Modulus (MPa) = 0.0981 × (56 + 7.66 × Shore A Hardness) Young’s Modulus (MPa) = 0.0981 × (56 + 7.66 × 70) Young’s Modulus (MPa) = 0.0981 × (536.2) Young’s Modulus (MPa) = 52.6 MPa
Therefore, for an elastomer with a Shore A hardness of 70, the corresponding Young’s Modulus is approximately 52.6 MPa.
Example 2: Converting Shore D Hardness to Young’s Modulus for a Plastic
Given:
- Shore D Hardness = 80
To calculate Young’s Modulus (MPa), we use the formula:
Young’s Modulus (MPa) = (-0.0057 × Shore D Hardness^3) + (1.8 × Shore D Hardness^2) + (32.7 × Shore D Hardness) + 28.6 Young’s Modulus (MPa) = (-0.0057 × 80^3) + (1.8 × 80^2) + (32.7 × 80) + 28.6 Young’s Modulus (MPa) = (-0.0057 × 512000) + (1.8 × 6400) + (2616) + 28.6 Young’s Modulus (MPa) = (-2918.4) + 11520 + 2616 + 28.6 Young’s Modulus (MPa) = 11246.2 MPa
Therefore, for a plastic with a Shore D hardness of 80, the corresponding Young’s Modulus is approximately 11246.2 MPa.
Example 3: Converting Shore A Hardness to Young’s Modulus for a Rubber Gasket
Given:
- Shore A Hardness = 45
To calculate Young’s Modulus (MPa), we use the formula:
Young’s Modulus (MPa) = 0.0981 × (56 + 7.66 × Shore A Hardness) Young’s Modulus (MPa) = 0.0981 × (56 + 7.66 × 45) Young’s Modulus (MPa) = 0.0981 × (400.7) Young’s Modulus (MPa) = 39.3 MPa
Therefore, for a rubber gasket with a Shore A hardness of 45, the corresponding Young’s Modulus is approximately 39.3 MPa.
These examples demonstrate how to calculate Durometer to Young’s Modulus, that can be used to convert durometer hardness values to Young’s modulus values for different materials.

What is Durometer to Young’s Modulus?
Durometer is a measure of the hardness of a material, typically used for rubbers, elastomers, and other non-rigid materials. It is expressed on a Shore scale, which ranges from 0 (softest) to 100 (hardest).
The most commonly used Shore scales are Shore A and Shore D, with Shore A being suitable for softer materials and Shore D for harder materials.
Young’s Modulus, also known as the Elastic Modulus, is a measure of the stiffness or elasticity of a material.
It represents the relationship between stress (force per unit area) and strain (deformation) in the linear elastic region of a material’s stress-strain curve.
Young’s Modulus is typically expressed in units of pressure, such as Pascals (Pa) or Pounds per Square Inch (PSI).
Durometer to Young’s Modulus Calculation Formula
The formula used to convert durometer hardness to Young’s modulus depends on the material type and the durometer scale. Here are two common formulas:
- For elastomers and rubbers (Shore A): Young’s Modulus (MPa) = 0.0981 × (56 + 7.66 × Shore A Hardness)
- For plastics (Shore D): Young’s Modulus (MPa) = (-0.0057 × Shore D Hardness^3) + (1.8 × Shore D Hardness^2) + (32.7 × Shore D Hardness) + 28.6
It’s important to note that these formulas provide approximate values, and the actual Young’s modulus of a material may vary due to various factors, such as temperature, strain rate, and material composition.

The Durometer to Young’s Modulus converter is a valuable tool for professionals working with elastomers, rubbers, plastics, and other non-rigid materials, enabling them to make informed decisions and optimize their material selections.
What is the formula for Young’s modulus of hardness?
The formula used to convert durometer hardness to Young’s modulus depends on the material type and the durometer scale used (Shore A or Shore D). Here are the two common formulas:
- For elastomers and rubbers (Shore A): Young’s Modulus (MPa) = 0.0981 × (56 + 7.66 × Shore A Hardness)
- For plastics (Shore D): Young’s Modulus (MPa) = (-0.0057 × Shore D Hardness^3) + (1.8 × Shore D Hardness^2) + (32.7 × Shore D Hardness) + 28.6
What is the difference between durometer and modulus?
Durometer and modulus are two different properties used to characterize materials:
- Durometer is a measure of the hardness of a material, specifically for rubbers, elastomers, and other non-rigid materials. It is expressed on a Shore scale, ranging from 0 (softest) to 100 (hardest), with Shore A and Shore D being the most common scales.
- Modulus, particularly Young’s Modulus, is a measure of the stiffness or elasticity of a material. It represents the relationship between stress (force per unit area) and strain (deformation) in the linear elastic region of a material’s stress-strain curve. Young’s Modulus is typically expressed in units of pressure, such as Pascals (Pa) or Pounds per Square Inch (PSI).
In simple words we can say that, durometer measures hardness, while modulus (specifically Young’s Modulus) measures elasticity or stiffness.
How do you calculate Young’s modulus of rubber?
To calculate the Young’s modulus of rubber, you need to know the Shore A hardness value of the rubber sample. Then, you can use the following formula:
Young’s Modulus (MPa) = 0.0981 × (56 + 7.66 × Shore A Hardness)
This formula is specifically designed for elastomers and rubbers using the Shore A hardness scale.
For example, if the Shore A hardness of a rubber sample is 70, you would calculate the Young’s Modulus as follows:
Young’s Modulus (MPa) = 0.0981 × (56 + 7.66 × 70) Young’s Modulus (MPa) = 0.0981 × (536.2) Young’s Modulus (MPa) = 52.6 MPa
Therefore, for a rubber sample with a Shore A hardness of 70, the corresponding Young’s Modulus is approximately 52.6 MPa.
