Line 6:

:NPU = ((0.16 × (24 hour protein intake in grams)) - ((24 hour urinary [[urea]] nitrogen) + 2) - (0.1 × (ideal body weight in kilograms))) / (0.16 × (24 hour protein intake in grams))

As a value, NPU can range from 1 to 0, with a value of 1 indicating 100% utilization of dietary nitrogen as protein and a value of 0% an indication that none of the nitrogen supplied was converted to protein.
