US Pint (pt)
The US pint, symbolized as pt, is equal to 1/8 of a US gallon, or approximately 473 milliliters. Derived from British units, it became standardized in the US after independence. Pints are commonly used for beverages like beer and milk in the United States. Unlike the British imperial pint (568 mL), the US pint is smaller, creating distinctions in international trade and cultural habits. Despite metrication globally, the pint remains a familiar and enduring unit of measurement in everyday American life.
Cubic Inch (in³)
The cubic inch, symbol in³, is a US customary and imperial unit representing the volume of a cube with each side one inch in length. Its use dates back centuries in English measurement systems. Today, it is particularly significant in the automotive industry, where it historically defined engine displacement before metric liters became common. One cubic inch equals 16.387 milliliters, making it a small but practical unit for precision engineering, manufacturing, and certain niche applications.
