Resting energy at that weight is about 366 kcal per day. The Merck neutered-adult factor of 1.6 puts maintenance near 586 kcal before activity is added. The dog food calculator on this page uses that same resting-energy formula, then applies the activity and size adjustments from the main dog food calculator.

Reading the portions

Compared with other single-size small breeds, that neutered-adult portion is 92 kcal higher than the 494 kcal for an average small breed at 16 lb.

Portions are a starting estimate. Scottish Terrier individuals can vary by body condition, neuter status, and how much they work. Adjust the bowl from what you see on the ribs, not from the table alone.
