The calculation
14 fl oz × 29.57 = 414 g of water × 0.86 = 356 g full · × 90% = 320 g
Candle wax weighs about 0.86 times as much as the same volume of water (fill-weight rule). The fragrance oil is part of that fill, so the wax is the fill weight divided by (1 + fragrance load). Your jar may hold slightly more or less than its label — fill it with water and weigh it for an exact figure.
By fragrance load
| Fragrance load | Wax | Fragrance oil |
|---|---|---|
| 6% of wax | 302 g (10.66 oz) | 18.1 g (0.64 oz) |
| 8% of wax | 297 g (10.47 oz) | 23.7 g (0.84 oz) |
| 10% of wax | 291 g (10.28 oz) | 29.1 g (1.03 oz) |
For a batch (8% fragrance)
| Candles | Wax | Fragrance oil |
|---|---|---|
| 6 | 1,780 g (3.92 lb) | 142 g (5.0 oz) |
| 12 | 3,561 g (7.85 lb) | 285 g (10.0 oz) |
| 24 | 7,121 g (15.70 lb) | 570 g (20.1 oz) |
Check the maximum fragrance load for your wax — commonly 10% for container soy waxes and up to 12–15% for some blends (see the candle calculator table).
