Force Units

International System of Units (SI)

In the international system of units, a unit of force is 1 Newton.
  It is defined as a force that changes the velocity of a body 1 kg per 1 m / s in 1 s per second in the direction of the force, i.e. 1 N = 1 kg · m / s².

• 1 meganuton [MH] = 1000 kN
• 1 Kilonewton [kN] = 1000 N
• 1 Newton [N] = 1000 mN
• 1 Millinewton [mH] = 1000 μN

Non-SI Units

• 1 Ton-force [tf] = 1000 kgs = 9806.65 N
• 1 Kilopond [kp] = 9.80665 N
• 1 Kilogram-force [kgf] = 9.80665 N
• 1 Grave force [Gf] = 9.80665 H
• 1 Gram-force [gf] = 0.001 kgs = 9.80665·10-3 N
• 1 Milligrave force [mGf] = 0.00980665 N
• 1 Milligram-force [mgf] = 9.80665 μN
• 1 Dyne [dyn] = 1 g·cm/s² = 10^-5 H = 1,0197·10^-6 kgf

Imperial and Customary units

• 1 Ton-force (short) [tf] = 8896.443230521 H
• 1 Pound force [lbf] = 4.44822168 H
• 1 Ounce-force [ozf] = 0.27801385095378125 H
