This page converts urea. BUN (blood urea nitrogen) counts only the nitrogen in urea: BUN in mg/dL is about half of urea in mg/dL, and BUN converts with a different factor. Check which one your form prints.

Frequently asked questions
What is the formula to convert urea?
mmol/L = mg/dL × 0.1665. To go the other way, divide instead of multiply.
How do I convert mmol/L to mg/dL?
mg/dL = mmol/L × 6.006006. It is the same conversion in reverse - type a value in the mmol/L field above and the mg/dL value appears instantly.
Which unit does my country use for urea?
Israeli lab forms usually print urea in mg/dL, while Russia and much of Europe use mmol/L. US labs usually report BUN instead, which is a different number.
Does converting change what my result means?
No - it's the same value in a different unit. Always compare it to your own lab's reference range and discuss with your doctor.
