1 Gallon = 128 ounces, so 1/20 of 129 = 6.4 ounces (call it 6 1/2 ounces).
1 gallon = 128 fluid ounces 1/50 of a gallon = 2.56 fluid ounces
6.4 ounces for each gallon of gas.
There is a very simple solution to find your ratios. There are 128 ounces in a gallon and since we are always using a ratio of 1 for the gas all you need to do is divide 128 by the gas side of the ratio. The standard ratio seems to be 40 to 1 (40 : 1) gas to oil in which case we divide 128 by 40 and get 3.2. This means you need 3.2 ounces of oil for every gallon of gas. (128 / 40 = 3.2) I am confused as to whether you are asking for a 125 to 1 ratio or are confused and mean a 1 to 25 ratio. Here are a few values for gas mixing. 125 : 1 ratio is 1.024 ounces per gallon of gas 25 : 1 ratio is 5.12 ounces per gallon of gas 50 : 1 ratio is 2.56 ounces per gallon of gas 40 : 1 ratio is 3.20 ounces per gallon of gas
6 ounces
4 ounces of oil to 1 gallon of gas.
5.5 ounces to a US Gallon which is 128 ounces. 24 divided into 128 = 5.33
1 US gallon = 128 fluid ounces. in a 100 to 1 ratio you would need to add 1.28 fluid ounces.
Since there are 128 ounces in a gallon, to get a 25:1 mix using 1 gallon of gas means you need 128/25 = 5.12 ounces of oil.
Googling "one gallon in ounces" gives you 128. 1/16 of that is 8. So for each gallon of gas you'd need a measuring cup of oil.
38.4 ounces
1 to 16
2.6 ounces of oil per gallon of gas. A 50 to 1 ratio.
