10 Megapascals to KSI: Unlocking the Power of Pressure Conversion

Understanding the Relationship

Pressure is a fundamental physical quantity that measures the force applied perpendicularly to a surface per unit area. Two widely used units of pressure are megapascals (MPa) and kilopounds per square inch (ksi).

1 megapascals (MPa) = 0.145038 ksi

Conversion Tables

Megapascals (MPa) to Kilopounds per Square Inch (ksi)

Conversion Formula:

ksi = MPa x 0.145038
