| 90 | 360 hours |
What each input means
- Wax Weight
- Weight of wax in the candle in ounces. An 8 oz container typically holds ~6-7 oz of wax.
- Burn Rate
- Wax consumption rate in oz per hour. Soy ~0.25, Paraffin ~0.35, Beeswax ~0.20 oz/hr for a standard wick.
- Wick Size Factor
- Wick size adjustment: 0.7 = small/underwicked (slower burn), 1.0 = correct size, 1.3 = large/overwicked (faster burn).
