Far and Near
In this unit, we will explore concepts related to 
measurement and distance. We will begin by 
understanding how we perceive distances, both close 
and far.

and far.
Basic Units of Length
Millimetre (mm): Used for very small things (screws, sprouts, nails).
Centimetre (cm): Used for small objects (mobile phone, handkerchief).
Metre (m): Used for medium/large objects (door height, elephant¾s trunk, depth of well).
Kilometre (km): Used for very large distances (roads, races, distance between cities).
Feet (ft) and Inches (in): Common in daily life, especially for height.

Conversion Rules
10 mm = 1 cm
100 cm = 1 m
1000 m = 1 km
1 inch = approx. 2.5 cm
1 foot = 12 inches j 30 cm

Different Units but Same Measure
Sometimes we can express the same length using different units:
204 cm = 2 metre 4 cm 540 cm = 5 metre 40 cm 240 cm = 2 metre 40 cm

Comparing Lengths
Always convert to the same unit before comparing.
Example:
5 m = 500 cm
So, 456 cm < 500 cm
Rule:
Use < (less than), > (greater than), = (equal to)
