The calculation

pace = 140 s ÷ 500 m = 0.2800 s/m · watts = 2.80 ÷ 0.2800³ = 127.6 W

This is Concept2’s formula (watts calculator). Calories use the widely documented monitor formula, 4 × 0.8604 × watts + 300 per hour, which assumes a 175 lb rower — see Concept2’s calorie calculator for the correction for your weight.
