What is API MPMS
API MPMS (API Manual of Petroleum Measurement Standards) is a comprehensive set of technical standards developed and published by the American Petroleum Institute (API).
It provides standardized procedures and best practices for the measurement, sampling, testing, and evaluation of crude oil, petroleum products, and related hydrocarbons throughout the petroleum industry.
Developed by the American Petroleum Institute (API), the Manual of Petroleum Measurement Standards (MPMS) establishes uniform procedures for measuring, testing, sampling, and analyzing crude oil, petroleum products, and related hydrocarbons. These standards are created and continuously updated by industry experts to promote consistent measurement practices and facilitate fair commercial transactions worldwide.
API MPMS standards are applied in numerous petroleum measurement activities, including determining the volume of crude oil stored in tanks, measuring petroleum quantities in marine tankers, railcars, and trucks, calculating density and specific gravity, determining viscosity, performing temperature and pressure corrections, and conducting custody transfer measurements. Their widespread adoption helps ensure accurate inventory management, regulatory compliance, operational efficiency, and confidence in commercial petroleum transactions across the global energy industry.
