The calculation
10 fl oz × 29.57 = 296 g of water × 0.86 = 254 g full · × 90% = 229 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 | 216 g (7.62 oz) | 13.0 g (0.46 oz) |
| 8% of wax | 212 g (7.48 oz) | 17.0 g (0.60 oz) |
| 10% of wax | 208 g (7.34 oz) | 20.8 g (0.73 oz) |
For a batch (8% fragrance)
| Candles | Wax | Fragrance oil |
|---|---|---|
| 6 | 1,272 g (2.80 lb) | 102 g (3.6 oz) |
| 12 | 2,543 g (5.61 lb) | 203 g (7.2 oz) |
| 24 | 5,087 g (11.21 lb) | 407 g (14.4 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).
