Calculate fragrance load for candles

Wax weight x fragrance load = oil weight.

That is the only formula most batches need. The rest is keeping units straight and writing the result on the batch card.

When the wax supplier lists a maximum load, treat that as the roof. Start lower unless you already know the wax, the oil, and the wick can handle more.
