A newton is equal to 1 kg⋅m/s 2, and a kilogram-force is 9.80665 N, [3] meaning that 1 kgf/cm 2 equals 98.0665 kilopascals (kPa). In some older publications, kilogram-force per square centimetre is abbreviated ksc instead of kg/cm 2.
The kilogram-force (kgf or kg F), or kilopond (kp, from Latin: pondus, lit. 'weight'), is a non-standard gravitational metric unit of force . It is not accepted for use with the International System of Units (SI) [ 1 ] and is deprecated for most uses.
In Germany, the kilopond lost its legal status as a unit of force on 1 January 1978, when for legal purposes the SI unit system was adopted. [3] A kilopond can be converted to the SI unit newton by multiplication with the standard acceleration g n: 1 kp = g n ⋅ 1 kg = 9.806 65 kg⋅m⋅s −2 = 9.806 65 N

The nit (nt) is a unit of luminance equal to one candela per metre squared (1 cd⋅m −2). The lambert (L) is a unit of luminance equal to 10 4 /π cd⋅m −2 . The lumerg is a unit of luminous energy equal to 10 −7 lumen-seconds (100 nlm s).
One kilopond is the force applied to one kilogram due to gravitational acceleration; this force is exactly 9.80665 N. This means 1 kp·m = 9.80665 kg·m/s 2 = 9.80665 N·m. A related unit is the kgf·cm , which is sometimes found in technical datasheets.
A newton is defined as 1 kg⋅m/s 2 (it is a named derived unit defined in terms of the SI base units). [1]: 137 One newton is, therefore, the force needed to accelerate one kilogram of mass at the rate of one metre per second squared in the direction of the applied force.
