Introduction
Measurement is essential in daily tasks like
buying fabric, cooking, and building.
It helps determine the exact amount needed
and ensures correct information sharing.
Example: Cooking needs proper measurement
for the right taste.
Without accurate measurement, tasks like

How Do We Measure?
Measuring with Body Parts (Old Method):
Handspan: Distance from thumb to little
finger when stretched.
Arm Length: Distance from shoulder to
middle finger tip.
Foot Length: Length of a person’s foot used
for measurement.
Stride: Steps used by farmers to measure

Problems with Using Body Parts for Measuring : 
Body parts differ in size from person to
person.
Measurements can vary when different
people measure the same object.
Example: Measuring a table with foot
lengths may give different results.
This highlights the need for standard units of
measurement.

Ancient Indian Measurement Systems : 
Ancient India used units like Angula (width of
a finger), Dhanusa, and Yojana for measuring
buildings, artifacts, and towns.
Angula is still used by traditional workers like
carpenters and tailors.
Harappan Civilization sites show evidence of
these ancient measurements through
markings on objects.
