We always recommend measuring by weight rather than volume so as to be precise when formulating. An easy way to see how this way of measuring helps with precision is looking at measuring 1 cup of water vs 1 cup of something fluffy like lavender buds. Example: 1 cup (volume) of water equals 8 oz (weight) of water while 1 cup (volume) of lavender buds equals 1 oz (weight) of lavender buds. As is done by manufacturers, the capacity of our containers are determined by volume not weight (this means that water is used as the unit of measure). For this reason, you may notice that the fill levels vary on our fragrances, flavor oils & carrier oils as they are all measured by weight. This difference in fill levels is simply due to the density & weight differences in each raw ingredient as noted above. Please Note: For your convenience, we have included a Volume Calculator conversion, but we recommend measuring by weight, not volume.
Just enter the weight measurement you wish to convert and it will automatically convert to the other weights given. For example, fragrance recommendations are usually given in ounces, but grams are much more accurate.
Calculate how much fragrance, essential oil, or additive to add to base
Great for figuring a weight percentage of your base. For example, when making 45 oz of soap and 5% fragrance is needed, just enter “45” in the “oz” section, then add “5” to “% of additive” and your weight of fragrance would be 2.25 oz.
Volume Calculator
Just enter the volume that you wish to convert. This is very helpful when you want to add ingredients using a pipette. Pipette measurements are in milliliters. If your recipe uses teaspoons or fluid ounces, this calculator will convert it to milliliters for you.
Colorant Calculator PPS
This calculator is for figuring additives when measured in teaspoons, this would be helpful for your dry additives such as colorants and exfoliants. A usage rate is required to use this section. For adding colorant and additives to soap, 1 tsp per pound of oils is a good rule of thumb, but it is better to have a specific recommendation.
There are two ways to calculate dry additives in soap. One is Per Pound of Soap (PPS) and the other way is Per Pound of Oils (PPO). You can see both our PPS and our PPO calculators below.
