Firlot

The firlot was a dry measure used in Scotland. For centuries it was the primary measure for all grains sold in the country. In the Scottish system a firlot was equal to 4 pecks, and the boll was equal to 4 firlots.

The first attempt of the Scottish Parliament to define the firlot was in 1426. They set it as 1,200 Scottish cubic inches or 19.98 litres, but effectively the exact volume continued to be defined by local custom and varied across the country.
