yeah except you're supposed to input mass in kg.

Let's assume a volume of an ellipsoid for your given "aura"- 4 inches off of their longest measurements. Average human is 177 cm tall so add 4 inches to half of that to get a radius of 98.66 cm.

Average man has a shoulder width of 18.25 inches, or 46.36 cm. Halve again and add the aforementioned 4 inches (10.16 cm) to get a radius of 33.34 cm.

4.12e5 cm^3 is our volume of air, but of course we have to subtract the volume of the human. That should be about 70 litres, or 70,000 cm^3, leaving us with 3.42e5 cm^3.

Density of fire is, as you said, 0.3 kg/m^3. So our mass would be about 0.1026 kg of actual fire. Also you read your sources wrong- they're 1100 F, meaning about 585 C. 585 - 23 = 562 C temp change.

You're looking at very nearly baseline 9-B with this feat.
