The floor area of the housing unit that is enclosed from the weather and heated. Basements are included whether or not they contain finished space.Garages are included if they have a wall in common with the house. Attics that have finished space and attics that have some heated spaceare included. Crawl spaces are not included even if they are enclosed from the weather. Sheds and other buildings that are not attached to the house are not included. "Measured" area means the measurement of the dimensions of the home, using a metallic, retractable, 50-foot tape measure.

Attached garages that are unheated and unheated areas in the attics and basements are also not counted.
Industry:Energy
The moisture content of air. Relative humidity is the ratio of the amount of water vapor actually present inthe air to the greatest amount possible at the same temperature.
Industry:Energy
Coal resources for which estimates of the rank, quality, and quantity have been computed, within a margin of error of less than 20 percent, from sample analyses and measurements from closely spaced and geologically well known sample sites. Measured resources are computed from dimensions revealed in outcrops, trenches, mine workings, and drill holes. The points of observation and measurement are so closely spaced and the thickness and extent of coals are so well defined that the tonnage is judged to be accurate within 20 percent. Although the spacing of the points of observation necessary to demonstrate continuity of the coal differs from region to region, according to the character of the coalbeds, the point of observation are no greater than 1/2 mile apart. Measured coal is projected to extend as a belt 1/4 mile wide from the outcrop or points of observation or measurement.
