# Psi To Durometer Converter

Pounds per square inch is abbreviated as Psi. It is also known as pound-force per square inch. It is a unit of pressure or of stress and measured based on avoirdupois units. Albert Ferdinand Shore is the one who defined durometer scale and invented a device to measure shore hardness. It is used to measure the hardness of polymers, elastomers and rubbers. Use this online Psi To Durometer converter to find the equivalent duro value from pounds per square inch.

#### Formula:

Shore A: a = ( 0.6403 / 0.0235 ) + ( (1 / 0.0235 ) * log10( ahname / 145 ) )
Shore D: a = log10( ahname / 145 ) - 0.5347 ) / 0.0235 Where, a = durometer b = psi

#### Example

Shore A has psi value of 200, then its equivalent durometer value is
a = ( 0.6403 / 0.0235 ) + ( (1 / 0.0235 ) * log10( 200 / 145 ) )
= 41
