English 101: Singular and Plural Forms in Measurement

Sometimes, it is really very hard to use the singular or plural form of words used in measurement such as foot, peso, dollar, year, minute, etc.

As a general rule, use the singular form of the words when they are used as ADJECTIVES (Pang-uri in Filipino); when the words are used as NOUNS (Panggalan in Filipino) use their plural form.

Examples:
1. Kris Aquino signed a three - year contract with ABS-CBN. (adjective)
2. His employment contract abroad is for two years. (noun)

3. Ana has a twenty-dollar bill. (adjective)
4. Watermelon costs three dollars a piece. (noun)
