Default kPa to in/Hg conversion

I'm fooling around with tuning my XFI and kPa has never been a term in my normal use. in/Hg has, since it's what is typically refered to ie: 16 in of vacuum.

One reading I had was 45kPa. Let's assume atm. pressure for the day was 30.0 in/Hg. 45kpa is 13.28 in/Hg.

30 in/Hg is 101.5 kPa. ( 1 atm)

101.5 kPa minus 45 kpa = 56.5 kPa.
56.5 kPa = 16.7 in/Hg vacuum...

therefor 45 kPa = 16.7 in/Hg vacuum.

anyone agree ?
