As a language expert with a focus on English and Chinese, I'm here to provide you with accurate and helpful information. When it comes to the question of whether it should be "2 feet" or "2 foot," the correct usage depends on the context and the rules of English grammar.

In English, the word "foot" can be used as both a singular and plural noun. However, when referring to a measurement of length, the plural form "feet" is typically used when the quantity is more than one. This is because we are not referring to a single foot, but rather to a measurement that is composed of multiple units of length.

Step 1: English Explanation

The international standard symbol for a foot is "ft" as per the International Organization for Standardization (ISO) 31-1, Annex A. This standard is widely recognized and used in various fields, including construction, engineering, and surveying.

When expressing measurements in feet and inches, it's common to use the plural form "feet" when the quantity is greater than one. For example, when measuring a length of 24 inches, it would be correctly expressed as "2 feet 4 inches" rather than "2 foot 4 inches." The use of the plural "feet" indicates that we are talking about a measurement that is made up of more than one unit of length.

The prime symbol (′) is sometimes used to denote feet, and the double prime (″) to denote inches. However, this notation is less common in everyday language and is more often found in technical or scientific contexts. For instance, "2 feet 4 inches" might be denoted as "2′4″," "2′ 4″," or "2′4″."

It's important to note that while the prime and double prime symbols can be used to represent feet and inches, they are not necessary for clear communication in most situations. The standard way to express this measurement in English is simply "2 feet 4 inches."

In summary, when referring to a measurement that consists of more than one unit of length, the plural form "feet" should be used. This follows the general rule in English that when a noun is used to express a quantity that is more than one, it should be in the plural form.
