Answer:
1) The metre is defined as the length of the path travelled by light in a vacuum in 1299 792 458 of a second. ... The metre was originally defined in 1793 as one ten-millionth of the distance from the equator to the North Pole along a great circle, so the Earth's circumference is approximately 40000 km.
Unit of: length
Unit system: SI base unit
SI units: 1000 mm; 0.001 km
2) Kilogram (kg), basic unit of mass in the metric system. ... A kilogram is very nearly equal (it was originally intended to be exactly equal) to the mass of 1,000 cubic cm of water. The pound is defined as equal to 0.45359237 kg, exactly.
3) The lower fixed point, or ice point, is the temperature of pure melting ice at normal atmospheric pressure. The upper fixed point, or steam point, is the temperature of pure boiling water at normal atmospheric pressure.
4) Temperature is a physical property of matter that quantitatively expresses hot and cold. It is the manifestation of thermal energy, present in all matter, which is the source of the occurrence of heat, a flow of energy, when a body is in contact with another that is colder. Temperature is measured with a thermometer.
5) a small medical thermometer with a short but finely calibrated range, for taking a person's temperature.
6)The surface area of a solid object is a measure of the total area that the surface of the object occupies. ... Smooth surfaces, such as a sphere, are assigned surface area using their representation as parametric surfaces
7) Mass is both a property of a physical body and a measure of its resistance to acceleration when a net force is applied. An object's mass also determines the strength of its gravitational attraction to other bodies. The basic SI unit of mass is the kilogram.
8) Length is a measure of distance. In the International System of Quantities, length is a quantity with dimension distance. In most systems of measurement a base unit for length is chosen, from which all other units are derived. In the International System of Units system the base unit for length is the metre.
9) Time is the indefinite continued progress of existence and events that occur in an apparently irreversible succession from the past, through the present, into the future. ... Time in physics is operationally defined as "what a clock reads".
