1 centimeter = 10 milimeters

1 decimeter = 10 centimeters = 100 millimeters

1 meter = 10 decimeters = 100 centimeters = 1 000 millimeters

1 kilometer = 1 000 meters = 10 000 decimeters = 100 000 centimeters = 1 000 000 millimeters

Area

1 square centimeter = 100 square millimeters

1 square decimeter = 100 square centimeters = 10 000 square millimeters

1 square meter = 100 square decimeters = 10 000 square centimeters = 1 000 000 square millimeters

1 are = 100 square meters = 10 000 square decimeters = 1 000 000 square centimeters

1 hectare = 10 ares = 10 000 square meters

1 square kilometer = 100 hectares = 10 000 ares = 1 000 000 square meters

Volume

1 cubic centimeter  = 1 000 cubic millimeters

1 cubic decimeter = 1 000 cubic centimeters = 1 000 000 cubic millimeters

1 cubic meter = 1 000 cubic decimeters = 1 000 000 cubic centimeters = 1 000 000 000 cubic millimeters

Weight / Mass

1 gram = 1 000 milligrams

1 kilogram = 1 000 grams = 1 000 000 milligrams

1 tonne = 1 000 kilograms = 1 000 000 grams = 1 000 000 000 milligrams
