Candle Fragrance Load Converter
Convert wax weight and fragrance load percentage into the fragrance oil amount to add to a candle batch. Get practical results in ounces, grams, milliliters, and teaspoons.
Convert wax and fragrance oil amounts
Use this for soy, coconut, paraffin, beeswax, and blended candle waxes. The default 6% load is a common starting point; your wax may allow less or more.
For the cleanest candle math, weigh fragrance oil instead of measuring it by spoon. Check your wax supplier's maximum fragrance load before going above 8–10%.
Candle fragrance oil chart
| Wax amount | 6% fragrance load | 8% fragrance load |
|---|---|---|
| 8 oz wax | 0.48 oz / 13.6 g oil | 0.64 oz / 18.1 g oil |
| 1 lb wax | 0.96 oz / 27.2 g oil | 1.28 oz / 36.3 g oil |
| 500 g wax | 30 g / 1.06 oz oil | 40 g / 1.41 oz oil |
| 1 kg wax | 60 g / 2.12 oz oil | 80 g / 2.82 oz oil |
How to use the converter
Enter your wax weight, choose the fragrance load your wax can handle, and measure that amount of fragrance oil by weight. A 6% load means 6 oz of fragrance oil for every 100 oz of wax.
If you only know how much fragrance oil you have, switch to “fragrance oil to wax” to estimate the wax batch size that matches your chosen percentage.
Candle fragrance load FAQ
What is a good fragrance load for soy candles?
Many soy candle recipes start around 6% fragrance load, then test higher or lower depending on the wax, jar, wick, and fragrance oil. Some soy waxes can handle 8–10%, but the supplier's guide should win.
Can too much fragrance oil hurt a candle?
Yes. Too much fragrance oil can cause sweating, poor burning, weak adhesion, wick trouble, or safety issues. Stay within the wax maker's recommended range and test small batches.
Does this converter include the fragrance oil in total candle weight?
The main formula compares fragrance oil to wax weight, which is the common quick calculation used by many candle makers. Total batch weight will be wax plus fragrance oil.
Why are milliliters and teaspoons approximate?
Fragrance oils do not all weigh the same per milliliter. This page estimates volume using 0.94 g/ml, which is useful for a quick sense check, but a scale is more reliable.
