Enter the total volume of the mixture and the mix ratio into the calculator to determine the amount of each component in a 40-1 mix ratio.

## 40-1 Mix Ratio Formula

The following formula is used to calculate the amount of each component in a 40-1 mix ratio.

A = T / (R + 1)
B = T - A

Variables:

• A is the amount of the first component (e.g., oil) B is the amount of the second component (e.g., gas) T is the total volume of the mixture R is the mix ratio (40 in a 40-1 mix ratio)

To calculate the amount of each component in a 40-1 mix ratio, divide the total volume of the mixture by the sum of the mix ratio and 1. This gives the amount of the first component. Subtract this amount from the total volume of the mixture to get the amount of the second component.

## What is a 40-1 Mix Ratio?

A 40-1 mix ratio refers to the proportion of two substances mixed together. It is commonly used in reference to the ratio of gasoline to oil in two-stroke engines, such as those in chainsaws or weed eaters. In this context, a 40-1 mix ratio means there are 40 parts gasoline to 1 part oil. This ratio ensures the engine is properly lubricated while running, without causing excess smoke or buildup.

## How to Calculate 40-1 Mix Ratio?

The following steps outline how to calculate the 40-1 Mix Ratio.

1. First, determine the total volume of the mixture (T).
2. Next, determine the mix ratio (R).
3. Next, calculate the amount of the first component (A) using the formula A = T / (R + 1).
4. Finally, calculate the amount of the second component (B) using the formula B = T – A.
5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem :

Use the following variables as an example problem to test your knowledge.

Total volume of the mixture (T) = 100

Mix ratio (R) = 40
