1000 hours = () days = () years 5 square meters 3 square centimeters = () square decimeters 30 liters = () square centimeters 2 square kilometers = () hectares 4.07m3 = () cubic decimeter

1000 hours = () days = () years 5 square meters 3 square centimeters = () square decimeters 30 liters = () square centimeters 2 square kilometers = () hectares 4.07m3 = () cubic decimeter

1000 hours = (41 2 / 3) days = (25 / 73) years
5 square meters 3 square centimeters = (500.03) square decimeters
30 L = (30000) CC
2 sq km = (200) ha
4.07 cubic meters = (4070) cubic decimeters

20 ha 200 m2 = () ha

1 m2 = 0.0001 ha
200 m2 = 200x0.0001 ha = 0.02 ha
So:
20 ha 200 m2 = (20.02) ha

3 square kilometers = () hectares 300 square decimeters = () square meters
3 square kilometers = () hectare 300 square decimeters = () square meters 7 square kilometers = () hectare = () square meters 19 million square meters = () hectare = () square kilometers
