What is moisture content?
Moisture content is the amount of water present in a substance. Whether it is soil, food, wood, or other materials, most things have water in some quantity. The moisture content of a substance is expressed as a percentage. It represents the ratio of the weight of water to the total weight.
The moisture content of a substance accounts for all forms of water, such as humidity, free, bound, or absorbed water. Understanding moisture content is crucial for determining a material's quality and usability.
For example, in food products, moisture content directly influences the texture, taste, and shelf life. In construction, the moisture content of materials like wood or concrete affects their strength and durability. Thus, knowing the moisture content is essential for maintaining the desired characteristics of a material.

How to use the moisture content calculator
The moisture content calculator is an easytouse tool. It is simple and straightforward and provides the results immediately. All you have to do is input the wet and dry weight. So, let's take an indepth look at how the tool works.

Input the weight of the substance while wet. It is measured in kilograms, but you may choose the unit from the list of options.

Input the weight of the substance after it dries.

The tool immediately displays the moisture content in percentage.

The best part is that you may input any 2 of these values, and the tool will instantly calculate and display the third one.

As a bonus, the calculator also gives you the water weight of the substance.
For instance, you input the weight while wet as 32 kg and the weight after drying as 19 kg. The tool tells you that the water weight is 13 kg, which means the moisture content of the substance is 40.625%.
Formula for moisture content
The formula for determining moisture content is similar to determining the percentage of a number, with a little more detail. Knowing the formula can be useful in various situations, such as when you can't use an online tool or in school, and your teacher decides to ask it in the class quiz.
The formula uses the moisture content equation as follows:
How to calculate moisture content
Now that we know the formula for calculating moisture content, let's examine it using an example.
Imagine you have some fresh chilies weighing 2.5 kg. You want to dry them to make chili powder, so you leave them in the sun to dry. After that, you weigh them and find out they are 1.3 kg. You become curious about the chilies' moisture content.
💡 Did you know that you can subtract the dry weight from the wet weight, and the result is the water weight of the substance?
Why do we need to calculate the moisture content?
Water significantly impacts various materials' physical and chemical properties, making it crucial to calculate moisture content. Below, we will share some critical reasons from multiple industries.

Quality control — In food production, too much moisture can lead to spoilage, while too little can affect texture and taste. Hence, a balanced moisture content needs to be maintained. Knowing the moisture content in pharmaceuticals helps maintain the stability and efficacy of the raw materials and finished products.

Safety — Moisture content is critical for safety in agriculture, construction, and manufacturing.

Environmental impact — Moisture content measurements can also contribute to environmental conservation. For instance, in wastewater treatment, managing the moisture content of sludge can improve the efficiency of treatment processes.
You might want to take a look at the potato paradox calculator, which is also based on the amount of water present in a substance and how it impacts the actual weight.
Applications of moisture content measurement
The importance of moisture content measurement traverses across various fields of life, including:

Agriculture
In agriculture, measuring moisture content is crucial for determining the optimal harvest time. Soil moisture content influences water use efficiency, so knowing the moisture content helps manage agricultural irrigation. 
Food Industry
Moisture content affects product texture, flavor, shelf life, and safety. Accurate measurement ensures compliance with industry standards. 
Construction
Moisture content measurement is essential for assessing the suitability of materials like wood, concrete, and soil. 
Pharmaceuticals
Precise control of moisture levels is essential for preventing the degradation of active ingredients. 
Environmental Science
Accurate moisture content measurements are required for studying soil properties, assessing the impact of climate change on ecosystems, and managing water resources.

What is the water weight of 110 kg potatoes?
The water weight of 110 kg of potatoes is 14 kg. You leave them to dry in the sun for a few hours, and they dry down to 96 kg.
The moisture content of the potatoes is 12.727%.
You can verify the results using a moisture content calculator.
Can I calculate the water content of 65 kg soil?
Yes, you can easily determine the moisture content of 65 kg soil.
Moisture content = ((Wet weight  Dry Weight) / Wet weight) × 100
First, you must modify the moisture content formula to determine water weight.
Water weight = Wet weight  Dry Weight
Now, imagine you are left with 39 kg after dehumidifying the soil. Substitute the values in the formula.
Water weight = 65  39
= 26 kg
How can I determine the moisture content of wood?
You may follow the steps below to determine the moisture content of wood or any other material that contains water and can be dried.

Note down the weight of the wood while it is wet.

Note down the weight after drying.

Subtract the dry weight from the wet weight. Here, you have the water weight.

Divide the water weight by the wet weight.

Multiply the result from step 4 by 100.

You have the moisture content of wood expressed as a percentage.
What is the moisture content of 2 kg dried apples?
Assuming the weight of these apples before drying is 7 kg, the moisture content is 71.43%.
Let's substitute the values in the moisture content equation:
Moisture content = ((Wet weight  Dry weight) / Wet weight) × 100
= ((7  2) / 7) × 100
= (5 / 7) × 100
= 0.71428 × 100
= 71.43%
