There are 7 fundamental units in S.I system .Thus ,for unit of length and mass and conversion ,
we can say that :
1 m =1000 mm .
So,3 mm=0.003 m
3 meters is 300 centimeters.
yes
Millimeters
0.58km
21 centimetors
it is the area where most metors of the earth fall,about 97 km above us.
the metors switch its form by talking to it
The outermost layer of the earth. It is a protective shield.
the solar system has many stars,some are planets,moons,asteoids,metors/meteorites, and planetoids.
the world is not strong enough and there will be a solar Eclipse and a 150,000 metors will hit around the world.(true fact)
We could live on the moon if we had unlimited oxygen. But it would be a rough life because of the metors that hit from time to time.
(1 inch = 25.4 mm)1 mile = (1760 * 36 * 25.4) / 1000 = 1609.344 metres
