I work it out by time. I figure that I get four hours of full flame on 1 liter of white gas. That is roughly 8 ounces per hour consumed. So, I simply think in terms of how long it takes to boil and cook, and I can estimate the amount of white gas needed.
White gas is a lot cheaper than other fuels, except for wood twigs. For groups or for lots of snow melting, that might be important.
