Engine pressure ratio airbus
Hello!
I just wanted to know what was the unit for engine pressure ratio! Pacal?
That's all for me.
Thanks,

There are no units for EPR for the obvious reason that it's a simple fraction of the pressure at the exhaust vs the pressure at the intake, so whether you measure those pressures in Pa, psi, N/m2 or anything else you please, the ratio will be the same.
