Conversion formula
The conversion factor from kilograms to pounds is 2.2046226218488, which means that 1 kilogram is equal to 2.2046226218488 pounds:
1 kg = 2.2046226218488 lb Daisydisk 4 6 5.
To convert 1.7 kilograms into pounds we have to multiply 1.7 by the conversion factor in order to get the mass amount from kilograms to pounds. We can also form a simple proportion to calculate the result:
1 kg → 2.2046226218488 lb
1.7 kg → M(lb)
Solve the above proportion to obtain the mass M in pounds:
M(lb) = 1.7 kg × 2.2046226218488 lb
M(lb) = 3.7478584571429 lb
The final result is:
1.7 kg → 3.7478584571429 lb
We conclude that 1.7 kilograms is equivalent to 3.7478584571429 pounds:
1.7 kilograms = 3.7478584571429 pounds

The kilogram-force (kgf or kgF), or kilopond (kp, from Latin: pondus, lit.'weight'), is a non-standard gravitational metric unit of force. It is equal to the magnitude of the force exerted on one kilogram of mass in a 9.80665 m/s2 gravitational field (standard gravity, a conventional value approximating the average magnitude of gravity on Earth).[1] Simple comic 1 7 download free. That is, it is the weight of a kilogram under standard gravity. Therefore, one kilogram-force is by definition equal to 9.80665N.[2][3] Similarly, a gram-force is 9.80665 mN, and a milligram-force is 9.80665 μN.
Kilogram-force is a non-standard unit and is classified in the International System of Units (SI) as a unit that is not accepted for use with SI.[4]
History[edit]
The gram-force and kilogram-force were never well-defined units until the CGPM adopted a standard acceleration of gravity of 9.80665 m/s2 for this purpose in 1901,[5] though they had been used in low-precision measurements of force before that time.The kilogram-force has never been a part of the International System of Units (SI), which was introduced in 1960. The SI unit of force is the newton.
Prior to this, the unit was widely used in much of the world and it is still in use for some purposes, for example, it is used for tension of bicycle spokes,[6] for informal references to pressure in kilograms per square centimetre (1 kp/cm2) which is the technical atmosphere (at) and very close to 1 bar and the standard atmosphere (atm), for the draw weight of bows in archery, and to define the 'metric horsepower' (PS) as 75 metre-kiloponds per second.[2] In addition, the kilogram force was the standard unit used for Vickers hardness testing.

In 1940s, Germany, the thrust of a rocket engine was measured in kilograms-force,[citation needed] in the Soviet Union it remained the primary unit for thrust in the Russian space program until at least the late 1980s.[citation needed]
The term 'kilopond' has been declared obsolete.[9]
Related units[edit]
The tonne-force, metric ton-force, megagram-force, and megapond (Mp) are each 1000 kilograms-force.
The decanewton or dekanewton (daN), exactly 10 N, is used in some fields as an approximation to the kilogram-force, because it is close to the 9.80665 N of 1 kgf.
