In parts of Scotland as late as the 18th century, a measure of dry capacity, = ½ peck, or ¹/₁₆th of a boll. In some localities the system of dry capacity measures was originally based on a local auchlet standard, but with the passage of time in practice the boll tended to be regarded as equivalent to the English quarter (8 Winchester bushels), and the auchlet was taken to be a sixteenth of that.

The auchlet was striken for some commodities, such as wheat, peas, and beans, and heaped for others, including oats, barley, and malt.

It also varied greatly with location; for example, an auchlet of wheat in Kirkcudbright Stewartry contained approximately 892 cubic inches (about 14.62 liters), while in Wigtonshire one auchlet of wheat was approximately 1075 cubic inches (about 17.62 liters).
