## Dye Lot Calculator

Calculate the percentage of yarn needed from a different dye lot:

To calculate the percentage of dye lot by current dye lot and new dye lot, you can use the following formula:

```
Percentage of dye lot = (New dye lot / Current dye lot) * 100
```

For example, if you have a current dye lot of 100 grams and you want to add 20 grams of a new dye lot, the percentage of the dye lot would be calculated as follows:

```
Percentage of dye lot = (20 grams / 100 grams) * 100 = 20%
```

This means that the new dye lot makes up 20% of the total dye lot.
