Mile radius size reference points: 5 mile radius covers about 78 sq miles, 10 mile radius covers about 314 sq miles, 15 mile radius covers about 707 sq miles, 20 mile radius covers about 1,257 sq miles, 25 mile radius covers about 1,963 sq miles, 30 mile radius covers about 2,827 sq miles, and 50 mile radius covers about 7,854 sq miles.
Acreage size reference points: 1 football field = about 1.3 acres; 640 acres = 1 sq mile;
12,800 acres = 20 sq miles; 32,000 acres = 50 sq miles; 96,000 acres = 150 sq miles; 320,000 acres = 500 sq miles; 480,000 acres = 750 sq mile.
Note about size reference points – fires rarely burn in nice even circles, therefore these reference points are general guides and the shape of the fire perimeter must be taken into account (e.g. a fire burn area may be significantly less than the 1,257 sq miles covered by a 20 mile radius yet extend beyond the 20 mile radius because the burn area is long but narrow).

Regional Fuel Conditions
Burning Index is a measure of fire intensity. It combines the Spread Component (a rating of the forward rate of spread of a head fire) and Energy Release Component (estimated potential available energy released per unit area in the flaming zone of a fire) to relate to the contribution of fire behavior to the effort of containing a fire.
100-Hour Fuel Moisture
100-Hour Fuel Moisture is computed from 24–hour average conditions composed of day length, hours of rain, and daily temperature/humidity ranges. It can also be used as a very rough estimate of the average moisture content of the forest floor from three-fourths inch to four inches below the surface.
