Enter the total electrical conductivity (EC) and the ${V2} into the TDS from EC Calculator. The calculator will evaluate the TDS from EC.

## TDS from EC Formula

The following two example problems outline the steps and information needed to calculate the TDS from EC.

**TDS = EC * .64**

Variables:

- TDS is the TDS from EC (PPM)
- EC is the total electrical conductivity (EC)

## How to Calculate TDS from EC?

The following steps outline how to calculate the TDS from EC.

- First, determine the total electrical conductivity (EC).
- Next, gather the formula from above = TDS = EC * .64.
- Finally, calculate the TDS from EC.
- 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 electrical conductivity (EC) = 30

TDS = EC * .64** **= ?
