Uric Acid Calculator converts your uric acid between different scales. Check mg/dL, µmol/L, and mmol/L. Then see if your uric acid is safe or dangerous.

Please note that this calculator is your tool to convert the scale used for your uric acid test results. But we also consider conversion when we look at gout treatments that transform uric acid to allantoin. So if you are concerned with that type of uric acid conversion, please see Uric Acid Converter.

Uric Acid Calculator Audience

I wrote Uric Acid Calculator for all gout sufferers. Because the most important fact for gout sufferers is blood uric acid level, and what it means.

Uric Acid Calculator from Safe to Dangerous

Uric acid concentration in the blood is the most important aspect of managing gout.

To manage gout properly, you must know your uric acid number, but you must also know what those numbers mean.

There are two common scales used to measure uric acid concentration. In the US, the most common scale is mg/dL (milligrams per deciliter). In Europe, the most common scale is mmol/L (millimoles per liter), and this SI unit is now the world standard in science, though mg/dL will continue in common use for some time. Occasionally, the standard scale is modified to µmol/L (micromoles per liter), which is one thousand times smaller.

To suit the common practice of most visitors, the GoutPal standard is to display mg/dL, with mmol/L in brackets.

I have included a uric acid conversion calculator below to convert between the two main scales, but first, a few words about typical values.

Typical Uric Acid Concentration

There is a great deal of confusion surrounding uric acid numbers. We know that uric acid crystals normally form at 6.8 mg/dL (0.4 mmol/L). Therefore, gout experts consider any value above this is to be high, though in practice, this is usually rounded to 7 mg/dL[1] (the SI unit is already rounded to 0.4 mmol/L).

The first element of confusion arises from lab reports assigning the “normal” range to results as high as 8 mg/dL. These are a result of sample averages that include gouty patients. So see Normal Uric Acid Levels for clarification. Remember, you should never be satisfied with a descriptive result – insist on knowing your exact uric acid number.

How to find your uric acid number.

Use the calculator to convert uric acid concentrations from one scale to the other. This is useful for your own numbers, and numbers that you read in articles on GoutPal.com and around the Internet.

All you need to do is type your uric acid number into the appropriate box, then press Tab or click the Convert button. Results are rounded to a couple of decimal points. But do not get bogged down in too much precision. Uric acid levels fluctuate, so you should always consider that you are in a range that can easily fluctuate by 10% up or down.

Convert Uric Acid mg/dL to µmol/L and mmol/L

Regardless of exact uric acid levels, these ranges are vital. You should always refer to safe; good; warning; and dangerous uric acid levels. Because these are more meaningful than statistical low; normal; and high.

mg/dL µmol/L mmol/L  Diagnosis
5 or less  300 or less  .30 or less  Safe
5 – 6  300 – 350  .30 – .35  Good
6 – 7  350 – 400  .35 – .40  Warning
Over 7  Over 400  Over .40  Danger

For all the details about converting uric acid measuring scales, please see the uric acid conversion guidelines.

Your Uric Acid Calculator

Now that you know the importance of your uric acid number, you should find out what it is as soon as you can. However, you treat gout (medical or alternative therapies) you must get uric acid tested at least once per year. This is best done by your doctor, but home test kits are also available.

The Gout Help sections and the Understanding Gout sections are full of advice on how to manage uric acid levels and what they mean.

If I update this calculator to improve reporting on different levels, or add other features, I will improve the version in the uric acid concentration guidelines.
