# Orders of magnitude (momentum)

The following table lists various orders of magnitude for momentum, in kilogram meters per second (kg·m/s).

## Table

Factor (kg·m/s) Value (kg·m/s) Item
1024 2×1024 An electron in a hydrogen atom[1]
100 1 A 420 gram football (FIFA specified weight for outdoor size 5) kicked to a speed of 8.6 km/h.
2.6 9x19 mm 7.5 gram pistol round launched at 350 m/s
3.8 5.56 mm (0.223) 4 gram rifle round launched at 945 m/s
5.83 A fast baseball pitched in the major league.[2][3]
6 The total impulse of a class C model rocket engine, which can be found in amateur fireworks.
6.52 Planck momentum, the unit of momentum in the system of Planck units[note 1]
101 16 The momentum of the famous football kick of the Brazilian player Roberto Carlos in the match against France in 1997. The football had a speed of 137 km/h, making it one of the hardest kicks measured.
