SI | IMPERIAL |
DISTANCE 1 metre (1 m) = 10 decimetres (10 dm) =100 centimetres (100 cm) =1000 millimetres (1000 mm) 1 decametre (1 dam) = 10 m 1 hectometre (1 hm) = 100 m 1 kilometre (1 km) = 1000 m | 12in.=1ft 3 ft = 1yd 5280 ft = 1 mile 1760 yd = 1 mile |
Conversions:
1 in. = 25.4 mm
1 ft = 30.48 cm
1 mile = 1.61 km
1 yd = 0.914 m
1 m = 3.28 ft
AREA
1 sq metre (1 m) = 10 000 cm = 1 000 000 mm 1 sq hectometre (1 hm) = 10 000 m = 1 hectare (1 ha) 1 sq km (1 km) = 1 000 000 m | 1 ft = 144 in. 1 yd = 9 ft 1 sq mile = 640 acre = 1 section |
Conversions:
1 in. = 6.45 cm =645 mm
1 m = 10.8 ft
1 acre = 0.405 ha
1 sq mile = 2.59 km

VOLUME 1 m = 1000000 cm = 1 x 10 mm 1 dm = 1 litre 1 litre = 1000 cm 1 mL = 1cm 1 m = 1000 litres | 1ft = 1728 in. 1 yd = 27 ft 1(liquid) U.S. gallon = 231 in. = 4 ( liquid) quarts 1 U.S. barrel (bbl) = 42 U.S. gal. 1 imperial gallon = 1.2 U.S. gal. |
Conversions:
1 in. = 16.4 cm
1 m = 35.3 ft
1 litre = 61 in.
1 U.S. gal. = 3.78 litres
1 U.S. bbl. = 159 litres
1 litre/s = 15.9 U.S. gal/min
Mass and Weight
1 kilogram (1 kg) = 1000 grams 1000 kg = 1 tonne | 2000 lb = 1 ton (short) 1 long ton = 2240 lb |
Conversions:
1 kg (on Earth) results in a weight of 2.2 lb
Density
Conversions:
S.I | IMPERIAL |
RELATIVE DENSITY In SI R.D. is a comparison of mass density to a standard. For solids and liquids the standard is fresh water. | In Imperial the corresponding quantity is specific gravity ; for solids and liquids a comparison of weight density to that of water. |
