1 kg =1000g.

1 km =1000m

1 m = 10 decimeter = 100 centimeter (cm)= 1000 millimeter (mm)

1 km = 0.62 1 mile.

1 m = 3.28 1 ft) = 1.094 yards.

1 DMM =1Mi Hu meter (cmm)= 1 silk =0.0 1 mm =0.00 1 cm.

1 cm) = 0.394 inch (inch)

1 cm =10mm.

1 decimeter (DM) =10cm.

Extended data:

1 km2 (km？ ) = 100 hectare (hm? ) = 247. 1 acre (ac)= 0.386 square miles (miles? )

1 m2 (m? ) = 10.764 square feet (feet? )

1 mu (a)= 100 square meter (m? ) = 10 hectare (hm? )

1 ha (hm ) =15mu =10000m2 (m? ) = 2.47 1 acre (ac)=0.0 1 km2.

(where h stands for 100 meter, huh? It means 100 meter squared)

1 square mile (mile? ) = 2.590 square kilometers (km? )

1 acre (ac)= 0.4047 hectare (hm? ) = 4.047× 10 km2 (km? ) = 4047 square meters (m? )

1 square foot? )= 0.093 m2 (m？ )

1 square inch (inch? ) = 6.452 square centimeters (cm? )

1 square code (yd? )= 0.836 1 m2 (m？ )

1 mu = 2000/3m2 ≈ 666.666m2.
