1 US fl dr = 0.225586 in³. 5 US fl dr = 1.12793 in³. 10 US fl dr = 2.255859 in³. 25 US fl dr = 5.639648 in³. 50 US fl dr = 11.279296 in³. 100 US fl dr = 22.558593 in³.
What is Fluid Drams (US)?
Fluid Drams (US) (US fl dr) is a unit of volume. The US fluid dram equals 1/128 of a US fluid ounce or exactly 3.6967 milliliters. It is part of the US customary system for measuring small liquid volumes. The precise conversion is 1 fl dr (US) = 3.696691195 mL based on US standards [nist-cuu]. Derived from British apothecaries' measures, the US fluid dram was standardized in the 19th century for pharmaceutical and liquid measurements in the US customary system. It differs slightly from the imperial fluid dram due to system variations [nist-cuu]. The US fluid dram remains in use in the United States for pharmacy, nutrition labeling, and some manufacturing processes. It is uncommon outside the US, where metric milliliters are preferred [nist-cuu].
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
People often search for this conversion using these alternate spellings: fluid dram us, fluid drams us, fluid drams (us), fl dr us, cubic inchs, cubic inchers, cubic inhes, cubic inchs, cubicinches. All of these refer to the Fluid Drams (US) to Cubic Inches conversion.
