Best Soap Calculator

Lye Soap Calculator

Calculating  your oils, lyes and the size of the mold needed when making your own soap needs to be pretty accurate for your soap to turn out well.  There are some really good online calculators.

I have used Majestic Mountain Sage Lye Soap Calculator for a long time and I think it is the best soap calculator.


I like that fact that you can calculate using ounces, pounds or grams.

It also gives you the option of using Sodium Hydroxide or Potassium Hydroxide in your calculations.

Other options when calculating your recipes are adding Sodium Lactate, which helps to make a firmer bar.

Sodium Lactate is a natural ingredient that comes from beets and corn.

You can also have the basic soap instructions print out when you create a recipe with MMS calculator as well as a place to add what liquid you intend to use and fragrances.

Fragrance and Measurement Converters

This calculator allows you to enter your recipe and print it out for future reference

Below you will find links to other calculators from MMS, which include a Lye Calculator, Fragrance Calculator and a Measurement Converter.

The Measurement Converter is a great.I have used this calculator often, it includes weight, volume, length and temperature converters.

There is also a box volume converter and a cylinder converter which I found very helpful when I bought my new cylinder molds for shaving soap.

    This is a very informative page. I learned a great deal about measuring lye soap. It is most effective in getting to the point in this regard and makes your entire presentation very attractive.

    Your selection of images also is top notch and appropriate. They all add to the effectiveness of your site.

    In my humble opinion this is a fine page.
