## Linear

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
