When to Spell Out 300 and When to Use the Numeral

As a general rule, whole numbers that are less than 999 are spelled out in text, especially when they appear at the beginning of a sentence. Thus, in most cases, it’s preferred to write ‘three hundred’ instead of ‘300’. However, when dealing with technical writing, statistical data, or when the number appears as part of a larger figure, numerals should be used for clarity, such as ‘300 kg’ or ‘2,300 participants’.
