(: Pooja, you may like to add this useful tables to Math Tables and Formulas. It would be great. Any help you need, please let me know. Gladys Gahona --chela5808 17:43, 23 January 2009 (UTC))

The Metric System

In the Metric system Metre is the unit measure of length, Are for surfaces, the Spere for solids, the Litre for capacity, the Gramme for weight.

Linear Measure

10 millimeters (mms) = 1 centimetre (cm)
10 cms = 1 decimetre (dm)
10 dms = 1 metre (m)
10 ms = 1 decametre (Dm)
10 Dms = 1 hectometre (Hm)
10 Hms = 1 kilometre (km)
10 kms = 1 Myriametre (Mm)

Surface or Square Measure

1 are = 100 square (sqs) metres
1 decare = 10 ares
1 hectare = 100 ares
1 deci-are = 1/10 of an Are
1 centi-are = 100 of an Are

Measure of Capacity

1 litre = 1000 cubic centimeters (c.c)
1 decalitre = 10 litres
1 hectolitre = 100 litres
1 kilolitre = 1000 litres
1 decilitre = 1/10 of a litre
1 centilitre = 1/100 of a litre
1 mililitre = 1000 litres

Measure of weight

10 milligrammes = 1 centigramme
10 centigrammes = 1 decigramme
10 decigrammes = 1 gramme
10 grammes = 1 decagramme
10 decagrammes = 1 hectogramme
10 hectogrammes = 1 kilogramme

British Weights and Measures

Avoirdupois Weight

2711.32 grains = 1 dram
16 drams = 1 ounce
16 ounces = 1 pound (lb.)
28 pounds = 1 quarter
4 quarters = 1 hundred-weight (cwt.)
20 cwt = 1 ton

Troy Weight

4 grains = 1 carat
24 grains = 1 penny-weight (dwt.)
20 dwts = 1 ounce
12 ounces = 1 pound
25 lbs = 1 quarter
100 lbs = 1 cwt
20 cwts = 1 ton of gold or silver

Apothecaries’ Weight (Dry)

20 grains = 1 scruple
8 scruples = 1 drachm
8 drachms = 1 ounce
12 ounces = 1 pound

Dry Measures

4 gills = 1 pint
2 pints = 1 quarter
2 quarters = 1 bottle
2 bottles = 1 gallon
2 gallons = 1 peck
4 pecks = 1 bushel

3 barely corns = 1 inch
12 inches = 1 foot
3 feet = 1 yard (yd.)
5 ½ yds = 1 pole
4 poles or 22 yds = 1 chain

Miscellaneous Measure of Length

League = 3 miles
Degree = 60 geographical or 69.121 Statute miles
Inch = 72 points, 12 lines
Nail = 2 ½ inches

Foot = 12 inches
Cubit = 18 inches
Yard = 36 inches
Pace = 2 feet 6 inches
Fathom = 6 feet
Rod = 5 ½ yards
Cable’s length = 100 fathoms = 600 feet
Furlong = 40 rods = 22 yards
Mile = 8 furlongs = 80 chains = 320 rods = 1760 yards = 5280 feet = 63360 inches

Square Measure

144 sq. inches = 1 sq. foot
1296 sq. inches = 9 sq. ft. = 1 sq. yard
1 sq. rod = 30 ¼ sq. yards = 272 ¼ sq. ft.
1 sq. chain = 16 sq. rods = 484 sq. yards = 4356 sq. ft.
1 sq. mile = 640 acres

Cubic Measure

Cubic foot = 1728 cubic (cu.) inches
Cubic yard = 27 cu. ft.

Measure of Time

60 seconds = 1 minute
60 minutes = 1 hour
24 hours = 1 day
7 days = 1 week
28 days = 1 lunar month
28 to 31 days = 1 calendar month
12 calendar months = 1 year
