Question Boost Gauge Reads in MPa not PSI??

My boost gauge has readings going from -.1 , -0.5 , 0 , 0.5 , .1 , .13..

Normally at full boost needle gets to about 0.9..

Is there a conversion that I can do to work out PSi reading??

Any input would be useful.. Rubbish Pic, but you get the idea..

Is the gauge not reading in Bar ??

AFAIK 1 BAR = 14.7 PSI so multiply by 14.7 for PSI

There again I might be wrong as I took my O Levels in 1976

If this is correct then 0.9 BAR on full boost seems a tad low even when standard

Hi mate,

The Gauge reads in MPa..

looking at some pics people have posted in, generally gauges read in P.S.I.

Also P.S.I seems to be the measuring unit/scale when talking about boost...?

Cheers

Harps.

0.1 MPa = 1 bar
