10 millimeters (mm)  = 1 centimeter (cm)
10 centimeters            = 1 decimeter (dm)
10 decimeters              = 1 meter (m)
1000 meters                = 1 kilometer (km)
1000 millimeters         = 1 meter
100 centimeters           = 1 meter
10 decimeters               = 1 meter
1/10000 kilometers     = 1 meter

Weight.

1000 grams (g)   = 1 kilogram (kg)

Money.

In Great Britain people use pounds (£) and pence (p). The coins are 1 penny, 2 pence, 5 pence, 10 pence, 20 pence and 50 pence. There are also £1 and £2 coins. The coins are round. But two coins have got seven sides. The little coin with seven sides is the 20-pence coin and the big one with seven sides is the 50-pence coin. There is a portrait of the Queen of England on every coin. There are £5, £10, £20, and £50 banknotes.
In the USA people use dollars ($) and cents (c). American coins are sometimes called change. Each coin has its own name. A one cent coin is called a penny. A 5-cent coin is called a nickel. There are 1, 2, 5, 10, 20, 50 and 100- dollar banknotes in the USA. You can see a portrait of an American president on one side and a picture of a famous building on the other.

1 yard = 3 foot = 0.9144 (m)
1 furlong = 220 yard = 201.168 (m)
1 hand = 4 inch = 10.16 (cm)
