A 1 in x 6 in x 8 ft board of White Fir weighs about 8.7 lb (roughly 26 lb per cubic foot). Its Janka hardness of 480 lbf is harder than about 13% of the woods in our database.
Uses and working notes
Common uses: construction lumber, pulpwood, plywood, utility wood.
Durability: Poor decay resistance and little defense against insects, making it strictly an interior wood.
Workability: Works easily with most tools though drying can introduce defects; accepts glue, stain and finish well.

How these numbers were sourced
MOE (1,485,000 lbf/in2), Janka (480 lbf) and shrinkage (T 7.0%, R 3.3%) from The Wood Database, which cites the USDA FPL Wood Handbook. Specific gravity 0.42 is the 12% MC value (page lists basic 0.37, 12% MC 0.42). No dimensional change coefficient given: White Fir has no exact row in the FPL/Hoadley table reproduced by Popular Woodworking, so CT/CR are omitted. Region, uses, durability and workability summarized from The Wood Database. Price indicative.
