A thousandth is a fraction equal to one part per thousand, often expressed as the symbol ‰. It describes a quantity that is one-thousandth of a whole, or 0.001. For instance, a 1% discount on a $100 item would result in a $1 discount, since 1% is equivalent to a thousandth of the original amount. In measurements, a thousandth of an inch is known as a mil, commonly used in engineering and manufacturing to represent minute distances or tolerances.
