What is the basic unit of length answer?
In the Centimetre–gram–second system of units, the basic unit of length is the centimetre, or 1⁄100 of a metre.
Other non-SI units are derived from decimal multiples of the metre..
What are the 7 basic SI units?
The seven SI base units, which are comprised of:Length – meter (m)Time – second (s)Amount of substance – mole (mole)Electric current – ampere (A)Temperature – kelvin (K)Luminous intensity – candela (cd)Mass – kilogram (kg)
What is the SI unit of power?
wattPower (P) is the rate at which energy is transferred or converted. Thus, power equals work divided by time (P = W / t). The SI unit of power is the watt (W), in honor of Scottish inventor James Watt (1736 – 1819).
What is largest unit of length?
One gigaparsec (Gpc) is one billion parsecs — one of the largest units of length commonly used. One gigaparsec is about 3.26 billion ly, or roughly 114 of the distance to the horizon of the observable universe (dictated by the cosmic background radiation).
What SI unit means?
systeme internationaleThe International System of Units (abbreviated SI from systeme internationale , the French version of the name) is a scientific method of expressing the magnitudes or quantities of important natural phenomena. There are seven base units in the system, from which other units are derived.
How fast is a jiffy?
Harrison, the time it takes for light to travel one fermi, which is approximately the size of a nucleon. One fermi is 10−15 m, so a jiffy is about 3 × 10−24 seconds. It has also more informally been defined as “one light-foot”, which is equal to approximately one nanosecond.
