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.

## 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]
103 N
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]
105 N (100 kN) The average force applied by seatbelt and airbag to a restrained passenger in a car which hits a stationary barrier at 100 km/h [6]
106 N
meganewton (MN)
1.8 MN Thrust of Space Shuttle main engine at lift-off
107 N 34.02 MN Thrust of Saturn V rocket at lift-off
108 N 570 MN Simplistic estimate of force of sunlight on Earth [7]
109 N
1 giganewton (GN)
1020 N 1.98 × 1020 N Gravitational attraction between Earth and Moon [8]
1022 N 3.5 × 1022 N Gravitational attraction between Earth and Sun [9]
1044 N 1.21027 × 1044 N The Planck force
