How to Write Measurements in a Formal Paper
When you're writing a formal paper for school or work, you need to format measurements in the text using a specific method. The method of formatting measurements should fit with the formal content of the rest of the paper. Write measurements in a formal paper using the specific rules set forth in the AP style guide.
Use numerals for all measurements of weight and distance, regardless of the value of the number. If you write the number "7" in a formal paper, spell out "seven" because the number is less than 10. However, when "7" is a measurement, use the numeral and not the spelled-out word.
Type a space followed by the unit of measure. For example, if you are writing a paper about the height of a chair, write, "The chair was 4 feet in height."
Place a hyphen in between the number and unit of measure if the measurement is modifying an object. For example, if your sentence is formatted, "The [measurement] [object]...", write "The 4-foot chair..." with a hyphen.
