This goes for all sorts of mixture measurements. I need to mix gas/oil
for a weed whacker and a chain saw, and mix Roundup herbicide for
weeds. The container instructions invariably speak of fractions of
fluid ounces and so forth. When translated to SI, I find that it comes
down to simply a percentage, such as a 2% oil/gas mix and a 4% (I am
unsure of the number without checking the container where I have written
in the garage) mixture for Roundup. It is SO simple. I once wrote to
Monsanto about the Roundup instructions, and got back a reply with some
convoluted metric conversion instructions.

Obviously, I am preaching to the choir. But I had some straight gas
left over from lawnmowing season and my snowblower is 2 cycle and
needs an oil/gas mix. I mixed a small, slightly rich mixture in a
volumetric container to get it running in early December.
But I still had gas left over and it needed a refill. I have two
identical gas cans, so I weighed the empty as a tare weight and the
partially fully one. 1850 g - 641 g (tare weight) = 1209 g gasoline
Gasoline density is about 0.74 g/mL, so 1634 mL gasoline. My
snowblower likes 48:1, so 34 mL of oil
Would have been a PITA in pounds, gallons, fl oz.
Note: The gasoline isn't too old because I use my lawnmower in
November with bagger to pickup leaves. Last use is the day I put it
away and get the snowblower out and ready.
