Question

If the height of Ram is 170 cm, his height in SI unit will be____.

• A. 1.7 km
• B. 1700 mm
• C. 17 m
• D. 1.7 m

Answer 1

The correct option is D 1.7 m

The SI unit of length is metre(m).
Since the given height is in centimetre(cm), we have to convert it in metre.

We know that,
1 m = 100 cm Or 1 cm = 0.01 m
Therefore,
$170cm=\frac{170}{100}=1.7m$
Thus, the height of Ram in SI unit will be 1.7 m.
