Metric oil pressure gauge

My manual only refers to the Imperial one (odd though the same diagram that shows a PSI oil pressure gauge shows a KPH speedo...) and I can't seem to find an answer online. Does anyone know what the non-US oil pressure gauge units are? I have a feeling its kPa x100 but am not certain since math class has mostly fallen out of my head over the years. Mine is labelled 0, 3, and 5.4. Idle is in the "3" neighborhood, and the internets tell me 43 PSI is around 300 kPa.

Can anyone confirm?

Thanks!

I am not sure but my guess would be BAR. 1BAR = 14.5 PSI This would make the range on your guage 0PSI to 78.32PSI and that sound about right. Your math is also correct as 1BAR does = 100 KPA
