2. One newton is equal to the force needed to accelerate a mass of one kilogram one meter per second per second

Kilogram Force:

1. One-kilogram force is the force due to gravity on a mass of 1 kg.

Pascal:

1. SI unit of pressure, equal to one newton per square meter

Gram Force:

1. The gram-force is equal to a mass of one gram multiplied by the standard acceleration due to gravity on Earth
2. The gram force is a metric unit of force ($gf$).
