Q1.
Are the tape and rod similar to the scale that the elder sister has in her geometry box? What did mother mean by char angula?
Answer
Yes — all three are measuring instruments for length, but each is built for a different job. And char angula means “four finger-widths”, roughly 6 cm to 8 cm of extra cloth.
| Instrument | What it is like | Best used for |
|---|---|---|
| Metal measuring rod (shopkeeper) | A stiff, straight rod, usually one metre long | Cloth spread flat on a counter — straight lengths |
| Measuring tape (tailor) | A long, soft, flexible strip that can bend | Chest, waist, sleeve — lengths along a curved body |
| 15-cm scale (geometry box) | A short, stiff plastic ruler marked in cm and mm | A pencil, an eraser, lines in a notebook |
So they are similar in purpose — every one of them carries markings and tells you a length in the same units — but they differ in length and in stiffness.
What is char angula?
angula = the width of one finger
char angula = 4 × width of one finger
1 finger width ≈ 1.5 cm to 2 cm
So char angula ≈ 4 × 1.5 cm to 4 × 2 cm = 6 cm to 8 cm
char angula = 4 × width of one finger
1 finger width ≈ 1.5 cm to 2 cm
So char angula ≈ 4 × 1.5 cm to 4 × 2 cm = 6 cm to 8 cm
Deepa's mother wanted the uniform to be about 6–8 cm longer, so that it would still fit after Deepa grows a little more.
Why it happens: angula is one of India's ancient units of length, mentioned along with dhanusa and yojana in old texts and still used by carpenters and tailors. It is a body-based unit, so it is quick and handy — you always carry your fingers with you — but it is not the same for everybody. The tailor's four fingers may not equal your mother's four fingers.
Try This: Measure the width of your own index finger with a 15-cm scale, and then your father's or mother's. Write both in mm. The difference you find is exactly the reason the world needed standard units.
