Simple and QUICK question: What is the required pressure
for gyroscope, turn indicators etc. in PASCAL?

I went to: http://www.onlineconversion.com/pressure.htm

Entered quantity 5, chose from Inches of Mercury, and chose to Pascals.

And came up with about 17 kilopascals.

Your mileage probably won't vary much.

Thanks, and best regards to all
