# Durometer To Psi Converter

Durometer is one of the measurement for hardness of a material. Hardness is generally defined as the material's resistance to permanent indentation. Albert Ferdinand Shore is the who defined durometer scale and invented a device to measure shore hardness. Durometer is used to measure the hardness of polymers, elastomers and rubbers. Pounds per square inch states that pressure is relative to a vacuum rather than ambient atmospheric pressure. Pounds per square inch is abbreviated as Psi. This calculator let you to convert the durometer value to pounds per square inch.

Albert Ferdinand Shore is the who defined durometer scale and invented a device to measure shore hardness. Durometer is used to measure the hardness of polymers, elastomers and rubbers.

This calculator let you to convert the durometer value to pounds per square inch.

#### Formula:

Shore A: b = e ( a * 0.0235 - 0.6403 ) * 145
Shore D: b=e ( ( a + 50 ) * 0.0235 - 0.6403 ) * 145 Where, a = durometer b = psi

#### Example

Calculate pounds per square inch if durometer is 55 duro?
b = e ( 55 * 0.0235 - 0.6403 ) * 145
b= 278
b=e ( ( 55 + 50 ) * 0.0235 - 0.6403 ) * 145
b = 901
