P1xV1/T1=P2xV2/T2
Transposing.......
P1xV1xT2/T1xV2=P2
V1=V2 so cancel each other.
P2=( P1xT2)/T1
Reduce your variables by using same gauge.
Measure when cold not after a run so the ambient temperature is the variable.
You can then decide on cold/warm weather settings if you wish. F1 teams are very meticulous on pressures based on air/track temps but normal roadgoing is not critical.
Fun bit.......
Use Malvern air?
