• Conversion of weight (mass) units •

The kilogramm is the SI basic unit of the mass in kg and the symbol of mass is m.

Fill in the appropriate line the known weight value

The question: "What is the weight of one kilogram-force = 1 kilopond?" is easy to answer:
The kilopond (kgf) is old and there is no use. Do not think about it: One kilopond = 1 kp weighs exact 1 kilogram = 1 kg.
Who wants to know more: In 1960 the force unit kilopond (kgf) was changed to Newton in the SI system. 1kp = 9.80665 N.

Note: The Winchester bushel, formerly used in England, contained 2150.42 cubic inches equal to 4 pecks = 35.239072 litre,
being the volume of a cylinder 181/2 inches in internal diameter and eight inches in depth. The standard bushel
prepared by the United States Government and distributed to the States, hold each 77.6274 pounds of distilled
water, at 39.8 degree Fahrenheit. and 30 inches atmospheric pressure, being the equivalent of the
Winchester bushel. The imperial bushel now in use in England is larger than the Winchester bushel, containing
2218.2 cubic inches, equal 4 pecks, or 80 pounds of water at 62 degree Fahrenheit = 0.03636872 m3.

In the United States, a kip is a unit of mass that equals 1,000 avoirdupois pounds.

Avoirdupois weights

16 drams = 1 ounce
16 ounces = 1 pound
8 pounds = 1 butchers' stone
7 pounds = 1 clove
14 pounds = 1 stone
28 pounds = 1 tod
112 pounds = 1 hundredweight
364 pounds = 1 sack
2240 pounds = 1 ton
2 stones = 1 quarter
4 quarters = 1 hundredweight
20 hundredweight = 1 ton

Troy and apothecaries weights

1 ounce = 480 grains
1 ounce = 24 scruples
1 ounce = 20 pennyweights
1 ounce = 8 drams
