Force.png

The following list shows different orders of magnitude of force.

Since weight under gravity is a force - several of these examples refer to the weight of various objects. Unless otherwise stated, these are weights under average Earth gravity at sea level.

Contents

Below 1 N

Factor (N) Value Item
10-6
micronewton (μN)
1-150 μN Output of FEEP ion thrusters used in NASA's Laser Interferometer Space Antenna [2]
10-3
millinewton (mN)
24.5 mN Maximum weight of a mosquito
92 mN Thrust of the NSTAR Ion Engine tested on NASA's space probe Deep Space 1

1 N and above

Magnitude Value Item
newton (N) 1 N The weight of an average apple[1][2]
10 N 9.80665 N One kilogram-force, nominal weight of a 1 kg object at sea level on Earth
102 N 720 N Average force of human bite, measured at molars [3]

1 kilonewton (kN)
8 kN The maximum force achieved by weight lifters during a 'clean and jerk' lift. [4]
104 N 45 kN The force applied by the engine of a small car during peak acceleration [5]
