Etymology: The prefix "centi-" comes from the Latin "centum," meaning "hundred," the same root that gives us "cent," "century," and "centipede" (literally "hundred-footed," though the creature has far fewer or more legs than that). Its path into science is a product of the French Revolution. In 1795, France adopted the metric system, which was built on powers of ten, and its planners needed a naming scheme in which each prefix stated a multiplier. Borrowing Latin numerical stems, they attached "centi-" to the unit of length, the metre, to mean one hundredth of it, so a centimetre is a hundredth of a metre. The prefix entered English along with the metric units themselves, and its meaning has stayed fixed ever since. Unlike "cent" in the currency sense, which was once a fraction of a dollar and is still used that way, "centi-" carries no sense of value or money. It is a pure scaling device, and that precision is why it could be attached to almost any unit, from the centigram to the centilitre.
