Urea is a nitrogenous compound that plays a pivotal role in the human body. Produced in the liver as a waste product of protein metabolism, urea serves as an essential marker for kidney function and health. The ability to measure and track urea levels in the blood is vital for diagnosing and managing various health conditions. The Blood Urea Nitrogen (BUN) test is commonly used to assess kidney function, dehydration, and other metabolic disorders.

This calculator converts Blood Urea Nitrogen (BUN) results between mmol/L and mg/dL.
1 mmol/L of BUN = 2.8 mg/dL. Use this calculator to easily convert your BUN results.
Converted Value:
1. What is Urea?
Urea is a colorless, odorless compound that is produced in the liver through a process known as the urea cycle, also called the ornithine cycle. Urea is a primary nitrogenous waste product of protein catabolism. When proteins are broken down, their constituent amino acids release nitrogen in the form of ammonia. Ammonia is highly toxic to the body, so it must be safely converted into a less harmful substance—urea. Urea is then transported through the bloodstream to the kidneys, where it is excreted in the urine.
The urea cycle is essential for removing nitrogen waste from the body and maintaining the delicate balance of nitrogen compounds. If the body fails to eliminate urea properly, it can lead to a range of health issues, particularly kidney dysfunction. Urea’s presence in blood is measured through a Blood Urea Nitrogen (BUN) test.
2. Urea Metabolism in the Body
Urea metabolism is a complex biochemical process that begins with the breakdown of proteins into amino acids. During digestion, the body metabolizes proteins from food into amino acids, which are essential for various functions, including the construction of new proteins and the maintenance of tissue function.
As the amino acids are broken down in the liver, they release ammonia—a highly toxic compound. Ammonia is converted to urea via the urea cycle. This process involves several enzymes and intermediate compounds, including ornithine, citrulline, and arginine. The urea produced in the liver is released into the bloodstream, where it is filtered out by the kidneys and excreted in the urine.
The urea cycle serves to remove excess nitrogen from the body while maintaining a balance of other important molecules. The kidneys play a critical role in filtering the blood and ensuring that excess nitrogen is eliminated efficiently.
3. Blood Urea Nitrogen (BUN) Test: Understanding Its Role in Health
The Blood Urea Nitrogen (BUN) test is a common blood test that measures the concentration of urea nitrogen in the blood. It serves as an indirect marker of kidney function because the kidneys are responsible for filtering urea from the blood. In a healthy individual, the kidneys effectively remove urea from the bloodstream, maintaining stable BUN levels.
However, abnormal BUN levels can be an indication of a variety of medical conditions, such as:
- Kidney Dysfunction: Elevated BUN levels may suggest impaired kidney function, as the kidneys are unable to filter urea properly. Conditions like chronic kidney disease (CKD) and acute kidney failure often lead to high BUN levels.
- Dehydration: When the body is dehydrated, the kidneys conserve water and produce less urine, leading to a concentration of urea in the blood and an elevated BUN level.
- Liver Disease: Since urea is produced in the liver, liver disease can affect urea production, causing lower-than-normal BUN levels.
- High Protein Diet: A high-protein diet or excessive protein metabolism can lead to increased urea production, raising BUN levels.
Normal BUN levels generally range from 7 to 20 mg/dL (milligrams per deciliter) in adults. However, this can vary slightly depending on the laboratory and testing methods used.
4. Units of Measurement for BUN
The BUN test is commonly reported in two units: milligrams per deciliter (mg/dL) and millimoles per liter (mmol/L). Both units serve the same purpose, but they are used in different parts of the world and in different medical settings.
- mg/dL (milligrams per deciliter): This is the most common unit used in the United States and a few other countries.
- mmol/L (millimoles per liter): This is the unit commonly used in many European and international laboratories.
To ensure proper understanding and to make conversions easier, it’s important to know how to switch between these units.
5. Converting Between mg/dL and mmol/L
Understanding the relationship between mg/dL and mmol/L is essential for interpreting BUN test results accurately, especially when doctors or patients are dealing with different units of measurement. The relationship between the two units is governed by the molar mass of urea.
The molar mass of urea (NH₂CONH₂) is 60 g/mol. Since 1 mmol of urea equals 60 milligrams (mg), and 1 mmol/L of urea equals 60 mg/L, the conversion between mg/dL and mmol/L for urea is straightforward.
Using the provided data that 1 mmol/L of Blood Urea Nitrogen (BUN) is equal to 2.8 mg/dL, the conversion factor is 2.8.
- To convert BUN from mmol/L to mg/dL, multiply by 2.8.
- To convert BUN from mg/dL to mmol/L, divide by 2.8.
For example:
- A BUN value of 10 mmol/L would be converted to 28 mg/dL (10 × 2.8).
- A BUN value of 28 mg/dL would be converted to 10 mmol/L (28 ÷ 2.8).
These conversions are useful in ensuring that medical professionals and patients can accurately interpret lab results, regardless of the unit system used.
