How to calculate dilution ratios For 32 oz bottles?
To start, you will need to decide what dilution ratio you are needing along with container size you are going to be using. Such as a 32oz bottle, 128oz gallon jug, or any other containers that you know the ounces of.
Say we want to make a 32oz bottle with a 4:1 dilution (4 parts water and 1 part chemical). We know that 32oz is the total ounces that we can put into that bottle. Now, let’s figure out what part needs to be chemical and what part needs to be water.
The way to do this is to simply; add the ratio numbers together, and then divide the sum of the ratio numbers by the total ounces.
For example: a dilution ratio of 4:1 in a 32oz bottle. Take the ratio numbers of 4:1 and add them together, 4+1=5. Then, take the total ounces, which in this case is 32, and divide that by the 5. So, we have 32oz/5, which gives us 6.4oz of chemical.
To recap the calculation steps:
4:1 ratio in a 32oz bottle
4+1 = 5
32oz divided by 5 = 6.4oz
So, this means that we would need to put in 6.4oz of chemical and then fill the rest with water to make a 4:1 dilution ratio in a 32oz bottle.
Let's check the math on that to be sure. 6.4 x 4 = 25.6, now we need to add back the one, which is the 6.4 and we get 25.6 + 6.4 = 32. So this checks out!
Now lets do a 7:1 dilution for a 32oz bottle. Again, change the dilution ratio numbers to addition like this and solve it: 7+1=8. Then, divide 32oz by 8 and we get 4oz. So put 4 ounces of chemical into the bottle and fill the rest with water for a 7:1 dilution.
How about a 10:1 dilution ratio for a 32oz bottle? It’s the same exact way. 10+1=11 Then 32oz divided by 11 = 2.9oz of chemical.
Pretty easy huh!
How to calculate Dilution Ratios For gallon containers.
Now let’s say we want to use a gallon container. The first thing to know is that a gallon is 128oz. The process is exactly the same as the 32oz way.
To make a 5:1dilution ratio for a gallon, we add the ratio numbers of 5:1 together like this: 5+1=6. Then, take 128oz and divide that by 6 and we get 21.3333333 ounces. So, we would put 21.3oz of chemical in the container and fill the rest with water totaling 128oz to make a gallon of solution at a 5:1 dilution.
Let’s do a dilution ratio of 20:1. We add the ratio numbers: 20+1 and this gives us 21. Then, divide 128oz by 21 and that gives us 6.09 ounces of chemical and the rest would be the water for a total of 128oz.
Hope this helps someone out there!
