do you mean a kilo newton (kN)?? if so, it is 1000 Newtons (N), a measurement of the force applied. 1N is also equal to 1kg/m2
1 kgf = 9.8066 N So, 20 kN = 20 kN ∙ [1 000 N/kN] ∙ [1 kgf/9.8066N] = 2 039.4 kgf
15 kN = 15 x 1000 N = 15000 N
1.60 kn for a postcard to croatia, 3.10 kn for a letter to croatia, 3.10 kn for a postcard to any other country 7.10 kn for a letter to any other coutnry
Based on E-M Strength (120 kn) 45 KN 70 KN 90 KN 120 KN 160 KN 210 KN 320 KN etc
Sulphuric Acid requires, I believe 27.2ml to make a 1N solution.
0.065kN is 66.3kgf
3kN is about 305.9kgf
224.8 pounds.
0,1 T
1.961kN at Earth's surface.
1,428 kg
