## examples with solutions for weight units

### Exercise #1

$7.8T=?kg$

### Step-by-Step Solution

T represents ton,

One ton contains one thousand kilograms,

Therefore, in 7.8 tons there are

1000*7.8 = 7800

$7800$

### Exercise #2

$x_m=?km$

### Step-by-Step Solution

In one kilometer there are 1000 meters,

therefore one meter is one-thousandth of a kilometer.

$\frac{x}{1000}$
