Question

How many cups are equivalent to one pint?

Answer 1

Hint: Gallon is a unit of volume (capacity) used in many English countries and it equals around 4.5 liters in the UK and about 3.8 liters in the US. There are 8 pints in a gallon which is also equal to 16 cups. It may also be worth remembering that 1 gallon equals 4 quarts and there are 2 pints in every quart. 1 quart is also equal to 4 cups.

Complete step-by-step answer:
There are 8 pints in a gallon which can be compared to the fact that there are 16 cups in a gallon. From this relation, we can say that 16 cups = 8 pints. Dividing them by 8, we get:
2 cups = 1 pint.
Therefore, 2 cups are equivalent to 1 pint.
In contrast, a liter (a metric unit) is subdivided into milli-liters, which are a thousandth part $\left( \dfrac{1}{1000} \right)$ or $\left( {{10}^{-3}} \right)$ of a liter.
One quart is roughly equal to one liter.

Additional Information
The French revolution (1789 - 99) provided an opportunity for the French to reform their unwieldy and archaic system of many local weights and measures.
The units of the metric system, originally taken from observable features of nature, are now defined by seven physical constants being given exact numerical values in terms of the units. In the modern form of the International System of Units (SI), the seven base units are: meter (m) for length, kilogram (kg) for mass, second (s) for time, ampere (A) for electric current, kelvin (K) for temperature, candela (cd) for luminous intensity and mole for amount of substance. These, together with their derived units, can measure any physical quantity. Derived units may have their own unit name, such as the watt $\left( \dfrac{J}{s} \right)$ and lux $\left( \dfrac{cd}{{{m}^{2}}} \right)$ , or may just be expressed as combinations of base units, such as velocity $\left( \dfrac{m}{s} \right)$ and acceleration $\left( \dfrac{m}{{{s}^{2}}} \right)$ .

Note:Until 1976 an imperial (UK) gallon was based on the volume of 10 pounds (4.5359 kg) of water at 62 ${}^\circ F$ (17 ${}^\circ C$ ).
There are two types of US gallon: liquid and dry.
Both the US liquid and imperial gallon are divided into four quarts (quarter gallons), which in turn are divided into two pints, which in turn are divided into two cups, which in turn are further divided into two gills. Thus, both gallons are equal to four quarts, eight pints, sixteen cups, or thirty-two gills.
