Measurements by body parts are rough measurements.
Let's see some examples-
Length is the size of an object from starting to end point.
Units of Length are:-
Millimeter
Centimeter
Decimeter
Meter
Kilometer
inch
Measurement by Digit.
Measurement by Pace.
Measurement by Handspan.
Measurement by cubit
Femtometre the shortest unit of length.
We can measure the distance of one to another by units of length.
The equatorial circumference of Earth is 40,075 km.
We can measure distance between two cities or countries in metre(m) and kilometre(Km), using Google Maps.
Measuring weight means to measure the heaviness of a thing.
The amount of matter a thing consists of, is called its weight.
The gram(g) and kilogram(Kg) are two units used to measure weight.
The heavier side of a weighing scale moves down.
The units for capacity are litres (l) and millilitres (ml).
