- 1 psf (lbf/ft2) = 47.88 N/m2 (Pa)
How to Calculate Load in N?
If you have the mass in kg - the load in N can be calculated as
F = m g (1)
where
F = load (N)
m = mass (kg)
g = gravitational acceleration (9.81 m/s2)
Example - Calculate the Load from a 800 kg Pallet
The load from a pallet with mass 800 kg can be calculated as
F = (800 kg) (9.81 m/s2)
= 7848 N
= 7.8 kN
