BUN to Urea conversion
To convert from mg/dL of blood urea nitrogen to mmol/L of urea, multiply by 0.357 (each molecule of urea having 2 nitrogens, each of molar mass 14g/mol)
Urea [mmol/L] = BUN [mg/dL of nitrogen] x 10 [dL/L] / 14x2 [mg N/mmol urea]
convert BUN to urea in mg/dL by using following formula:
Urea [mg/dL]= BUN [mg/dL] * 2.14
(conversion factor derived by: MW of urea = 60, MW of urea nitrogen = 14x2 => 60/28 = 2.14)
factor = 2 for conversions in mmol (2 moles N per mole of urea):
BUN [mmol/L]= 2x urea [mmol/L]

I agree with BA, BUN (mmol/L) = Urea(mmol/L). What is the source you are referring to?

BUN [mmol/L]= urea [mmol/L]
This is what the source you referred to says.

To get BUN mg/dL from Urea mmol/L divide the Urea by 0.357
