Newton
The newton, N, is a SI derived unit for measuring force. The newton in SI base units is 1 N =1 kg⋅m⋅s −2 which is equivalent to mass over acceleration (m/a) [1].
One newton is the force required to accelerate a one kilogram mass at the rate of one metre per second squared, or change in velocity, in a given direction [1].
[1]
Other examples include: a kilogram of mass exerting an average of 9.8 N due to the gravity, the weight of an average adult exerts a force of about 608 N (608 N = 62 kg × 9.80665 m·s-2) [1].
It is common to see force expressed in kilonewtons (kN) where 1 kN = 1000 N. For example, 1 kN is the equivalent of about 102 kg under the force of gravity. Another example, a platform rated at 321 kilonewtons will safely support a load of 32,100 kilograms [1].
Pascal
The pascal, Pa, is a Si derived unit of pressure, used to quantify internal pressures, stress, the young's modulus and ultimate tensile strength. The pascal in SI base units is 1 Pa = 1kg·m-1·s-2 which is equivalent to one newton per metre square (N/m2) or one joule per metre cubed (J/m3) [2].
