What is Dram?
Dram (dr) is a unit of volume. The dram is a unit of mass and volume with varying definitions depending on context. In mass, the avoirdupois dram equals 1/16 of an avoirdupois ounce or approximately 1.77185 grams. In volume, the fluid dram equals 1/8 of a fluid ounce or about 3.6967 milliliters. Both forms are non-SI units still used in pharmaceuticals and cooking in the United States [nist-sp-811]. The dram originated from the ancient Greek 'drachma' as a unit of weight and currency. It was incorporated into the British imperial system and later the US customary system, primarily for apothecary measurements. The dram's dual mass and volume use developed historically for medicinal dosing [nist-sp-811]. The dram remains in limited use in US pharmaceutical prescriptions and some cooking recipes. It is recognized by the US National Institute of Standards and Technology but largely replaced by metric units globally. The dram is uncommon outside the US [nist-sp-811].
What is Cubic Inches?
Cubic Inches (in³) is a unit of volume. A cubic inch is a volume unit defined as the volume of a cube with edges one inch long. One cubic inch equals exactly 16.387064 cubic centimeters (cm³), or 0.000016387064 cubic meters (m³), based on the inch defined by international agreement. This unit is commonly used in the United States for measuring engine displacement and small volumes in manufacturing and engineering applications [nist-si-guide]. The inch originated from the British Imperial measurement system, with its volume form, the cubic inch, defined as the cube of the inch. The inch was standardized internationally in the mid-20th century to exactly 2.54 centimeters, which fixed the cubic inch conversion factor [nist-si-guide]. Cubic inches are primarily used in the United States and Canada for automotive engine sizes and small volume measurements. Industries such as aerospace, manufacturing, and appliance design often use this unit for precise volume specification [nist-si-guide].
Common Misspellings
