SAE J517 Appendix A B C cover MPa TO psi CONVERSION TABLE; HOSE CODES and REPLACEMENT RECOMMENDATIONS FOR 100R9, 100R10 AND 100R11 SPIRAL HOSES as follows:
Rationalized conversion pressures from MPa to psi for the 100R hoses that have the same pressures for every size. These reference pressures allow the user to relate the new MPa pressure
number to the former even psi number, 3000 psi relates to 21 MPa with the mathematically correct conversion being 21 MPa equal to 3045 psi. Allowing for the use of the most common available pressures this table will assist in relating the old psi numbers to the new ISO standards that will use either MPa or Bar.
