A fifth is a unit of volume formerly used for distilled beverages in the United States, equal to one fifth of a US liquid gallon, 4⁄5 quart, or 25 3⁄5 US fluid ounces (757 ml); it has been superseded by the metric bottle size of 750 ml, sometimes called a metric fifth, which is the standard capacity of wine bottles world-wide and is approximately 1% smaller.

The board-foot is a specialized unit of measure for the volume of lumber in the United States and Canada. It is the volume of a one-foot length of a board one foot wide and one inch thick.
Board-foot can be abbreviated FBM (for "foot, board measure"), BDFT, or BF. Thousand board-feet can be abbreviated as MFBM, MBFT, or MBF. Similarly, million board-feet can be abbreviated as MMFBM, MMBFT, or MMBF.
