From metric measurements for words that start with K we use the prefix kilo. There are thermometers that use the Kelvin scale to read temperatures compared to a hypothetical absolute zero.
I was surprised to find how many mathematical words begin with the letter K. Even the nautical term knot is in this short list.
Kelvin - a scale used on some thermometers to measure temperature.
Kilo - means “a thousand of.”
Kilobyte - 1000 bytes a unit of measurement for data on computers. Kilo means a thousand of.
Kilogram - 1000 grams. It is the weight of a special platinum rod in Paris that is used as the standard unit of measure for the metric system. A kilogram is about 2.2 pounds.
Kilometer - 1000 meters (a unit to measure length in the metric system). A kilometer is about 3280 feet. Kilo means “a thousand of.”
Kilowatt - 1000 watts and is a unit of measure for electrical power. Kilo means “a thousand of.”
Kinematics - a branch of mechanics dealing with the motion of rigid bodies without reference to their masses or the forces acting on the bodies.
Kite - a quadrilateral that has two sets of adjacent sides that are the same length and one set of opposites angles that are congruent.
Klein Bottle - a special bottle that only has one side. Most bottles have an inside and an outside. In a Klein bottle, the “inside” and the “outside” are the same side!
Knight’s Tour - a knight’s tour of a chessboard is a sequence of moves by a knight such that each square of the board is visited exactly once.
Knot - a curve in space formed by interlacing a piece of string and then joining the ends together; a unit of speed in navigation equal to one nautical mile per hour.
