Petrograd Standard

Petrograd Standard is an old Nordic measure for softwood timber. It measures 165 cubic feet, whereas a "London Standard" measures 270 cubic feet. The timber measurements also vary between Europe and the United States and also between the traditional measurement system from Northern Europe and the Metric system. In the U.S. the units of measurement are "1000 Board Feet" and in the metric system the unit is the "Stere" which is 1 cubic metre. Small logs of "fir" trees, called "pit props", are traditionally measured by the "intaken piled fathom" ("IPF"), 6 ft x 6 ft x 6 ft or 216 cubic feet.

• 1 std of board equals 165 (English) cubic feet or 1980 board foot, or 120 pieces 12′ × 11″ × 1½″, or 4.672 cubic meters.
• 1 std of round wood equals 120 cubic feet, or 3.398 m³

Note that Kristiania Standard is 5/8 of Petrograd Standard, and London Standard is 270 cu. ft.
