Most common conversions used in real life:

1. Length:

$1 \ km = 1000 \ m$

$1 \ m = 100 \ cm$

$1 \ m = 1000 \ mm$

$1 \ cm = 10 \ mm$

2. Weight:

$1 \ kg = 1000 \ g$

$1 \ g = 1000 \ mg$

3. Volume (Capacity):

$1 \ kl = 1000 \ l$

$1 \ l = 1000 \ ml$

Example:

1. Convert

$25.38 \ km$ to

$m$ .

$1 \ km = 1000 \ m$

To convert higher unit to lower unit, we need to multiply by power of

$10$ 's.

$25.38 \times 1000 = 25380$

Therefore,

$25.38 \ km = 25380 \ m$ .

2. Convert

$955 \ mg$ to

$g$ .

To convert lower unit to higher unit, we need to divide by power of

$10$ 's.

$1 \ g = 1000 \ mg$

$\frac{1}{1000}$

$g = 1 \ mg$

$\frac{955}{1000}$

$= 0.955$

Therefore,

$955 \ mg = 0.955 \ g$ .

3. Express

$56 \ ml$ in

$l$ .

To convert lower unit to higher unit, we need to divide by power of

$10$ 's.

$1 \ l = 1000 \ ml$

$\frac{1}{1000}$

$ml = 1 \ l$

$\frac{56}{1000}$

$= 0.056$

Therefore,

$56 \ ml = 0.056 \ l$ .
