We are given that the titanic is found 3,797 m below sea
level. This is simply equivalent to 3.797 km or 3.8 km when rounded off to one
decimal.
We should take note that the letter k in km means kilo and
a kilo is equivalent to 1000. So this means that for 1 km there is exactly 1000
m. So to convert, simply multiply a value with unit m with this conversion
factor. Conversion factor = 1 km / 1000 m
Depth of titanic = 3,797 m (1 km / 1000 m)
<span>Depth of titanic = 3.797 km = 3.8 km</span>
