here is a re-calculated computation ...
1 ounce = 29.6 cc or ml
using 8 lb/gal. for water calulation and FAA 6 lb/gal. for gas:
1 (US fluid) oz = 1 oz (avoir.)
1 (avoir.) lb = 454 grams
1 oz = 28.375 grams
1 oz of water weighs 1 oz @ 8 lb/gal.
1 cc of water weighs 0.034 oz @ 8 lb/gal.
1 oz of gas weighs 0.750 oz @ 6 lb/gal.
1 cc of gas weighs 0.025 oz @ 6 lb/gal.
550cc = 18.58 fluid oz.
550cc of gas weighs 13.935 oz or 0.87 lbs ...
figures may change slightly due to rounding effect and true weigh of fluids ... but these are a close approximation ...
Now, I am going back to hide in my cave and play with my calulator ...
GEEZ ... you would think this was rocket science ...
must be so smart I am getting stupid ... I wonder if Einstien ever had a senior moment?
now lets me see ... was that
C = sqrt(E/M)?
which in its own right is kind of stupid ... because the speed of light remains constant ... or I think it does ... since the is no real way to measure it that I know of?
I suppose its all relative ...
