Question

How can I memorize the metric system?

Answer 1

Hint :A metric system can be defined as the system of measurement which succeeded the decimalized system which is based on the metre and was introduced in France in the year $1790s$. The historical development of these systems concluded under the oversight of an International standards body.

Complete Step By Step Answer:
The metric system is the system of measurement which uses the meter, liter and gram as the base units of the length (distance), capacity (volume) and weight (mass) respectively. Metric systems are used to measure smaller or larger quantities. Generally, we use units derived from the metric units.
The mnemonic way to remember the metric system is “King Henry Died Drinking Chocolate Milk” which gives us the funny memorable way to keep the prefixes straight.
The statement includes an explanation of the following prefixes: kilo, hector, deca, centi and milli.

Note :
Units are the internationally accepted standards for measurements of the physical quantities.
Different types of system of units are –
SI (International system of units)
The SI units are the standards of measurement defined by the international system of units. There are basic seven SI units which comprises of –Length – meter, Time – second, Amount of substance- mole, Electric current – Ampere, Temperature – Kelvin, Luminous intensity – candela and Mass - kilogram
MKS (Meter-kilogram-second) system
MKS system is the system of units, where length is measured in meters, mass in kilogram and time in seconds. Generally, MKS systems are used in engineering and in advanced physics.
CGS (centimetre-gram-second) system
CGS system is the system of units, where length is measured in centimeters, mass in grams and time in seconds. Generally, CGS systems are used in theoretical studies of physics.
 It is very important to know the difference between the system of units and the conversional ratios between them. Since if we say mass of one it does not make any sense, also mass of one gram and one kilogram differs a lot as $1kg = 1000g$ .
