Explanation:
a) What is 500.2 mm in meters?
Each m has 1000mm. So:
1 m - 1000mm
x m - 500.2mm



So:

B. What is 6500 g in kilograms?
Each kg has 1000g. So:
1 kg - 1000g
x kg - 6500g




C. What is 35000 ks in megaseconds?
Each megasecond has 1000ks. So
1 ks - 1000ks
x ks - 35000ks




D. What is 21 in in meters? 1 in = 2.54 cm
1 in - 2.54cm
21 in - xcm


Each m has 100cm. So
1m - 100cm
xm - 53.34cm




E. 42.195 km to meters. (1 km = 1000 m)
Each km has 1000m. So:
1km - 1000m
42.195km - xm



F. The above to centimeters. (1 m = 100 cm)
Each m has 100cm. So
1m - 100cm
42195m - xcm



G. The above to inches. (2.54 cm = 1 in)
1 in - 2.54cm
x in - 4219500cm

H. What is 0.43 m in inches?
Each m has 100cm, so

1 in - 2.54cm
x in - 43cm




I. What is 185 cm in feet? 1 ft = 12 in
Each inch has 2.54cm
1 in - 2.54 cm
x in - 185 cm



1 ft - 12 in
x ft - 72.83 in




J. Water has a density of 1000 kg/m3. If I have 50 m3of water, how much mass does the water contain?(Density = mass/volume)



K. If I have 46 g of iron, which has a density of 7.874 g/cm3, how many cubic centimeters of iron do I have?




L. What is your height in centimeters?
I'm 6 feet = 72 in
1 in - 2.43cm
72 in - x cm


M. *How many cubic meters are in a liter of water?
