The last post emphasises even more the ease of using the metric system when measuring out percentages.

Once you have the ratio, it doesn't matter what measurement system you use! Lets measure in "glugs". One glug each of nitro and oil plus 3 glugs of methanol for a total of 5 glugs of fuel. A glug can be a cup, pint, quart or gallon (or millilitre, decilitre or litre). Just make sure that the final container is sized appropriately. The metric system is an advantage if you are working out a new ratio and are trying to calculate with mixed units i.e. ounces, cups, quarts and gallons.
