Dear Soap Coach: “ I made a batch of soap that i was not happy with and I think it was because of the scale that I purchased. Its the Cuisinart K 55  from bed bath and beyond. The scale gives me ounces with fractions and the instructions does not tell me how to convert it to decimals. I dont mind buying another scale but I would like to know which scale you have or may suggest that will be a great purchase ” – Taina B.

Thanks Taina for allowing me to post your question.  Crafting soaps can be a fun experience. It can also cost you money if you don’t have a proper scale to measure out your ingredients.

When choosing a scale there are a few things you want to look for:

Weight limits: It should be able to hold the weight of most of your soap batch sizes.  Scales have a weight limit.   If you are making 8 pound batches of soap then a scale that can weigh up to 11 pounds would be sufficient but if you are making 30 pound batches at a time then a scale that can weigh up to 35 pounds should be sufficient.  You want to make sure the scale can hold the weight of your container as well.

Accuracy: The scale should read in ounces and grams.  You will need it in grams if you want to try other recipes from other countries that use the metric system.  Look for a scale that reads to .1 ounces. That way you will get a 10th of an ounce readings.

Digital: You don’t want a spring scale. They are used for weighing food and are not accurate enough for soap making.

Tare Feature: This is a must have.  It will allow you to zero out the scale so you can continue to weigh out the other ingredients in your batch that will go in the same container.  So for example, you are weighing out your oils. You don’t want to have to measure each one of your oils individually.  It also allows you not to have to do the math in your head. If you are adding oils and then have to add how much the next oil plus the oils in the container equal your new weight.  Sometimes you can make a mistake in your mental addition.  A scale with a tare feature will eliminate that.

Platform Size: You want to make sure the base is large enough to hold your larger weighing containers.  It is not fun to have a container that is too big and covers the output panel and you can’t see the measurements. You also want to look for a platform that is made of stainless steel and not plastic.  Plastic can warp from heat and ingredients such as fragrance and essential oils.

Reading Panel: It should be large enough for you to easily read.

AC Adaptor: It is preferable that you have a scale that has an electrical connection.  Scales that operate only from batteries can run out on your in the middle of your weighing and you don’t want that to happen when soap making.

As you increase in batch production size you may have to get a scale that can read in larger weights.  You will want to make this investment to save you time and for better accuracy in your large soap making batches.


Here is a list of online resources to where you can purchase a quality soap making scale.
