A kilometre (km) is a measure of length or distance in 1-dimensional space while a millilitre (ml) is a measure of volume in 3-dimensional space. The two measure different things and, according to basic principles of dimensional analysis, conversion from one to the other is not valid without some addition information.
3km = 300,000
3km in a meter
3km= 3k meters k= 1,000 meters 3k= 3,000 meters 3km= 3,000 meters
3000
3000 m
1.86411358 miles
3km is always 3km it makes no difference if you run or walk
3km = 3000m Therefore 3km + 312m = 3312m Or 312m = 0.312km Therefore 3km + 312m = 3.312km
3000 meters are in 3km 1000 meters per km .
I think it's about 1.8 miles.
3km
3000m = 3km
