Pounds per square foot to kilonewtons per square meter
Type a value in psf to get it in kN/m² instantly.
0.1197kN/m²
Nothing on our list is smaller: a domestic roof is 6.3× heavier. That allows about 0.1526 people of 80 kg on every square meter.
Convert the other way: kN/m² to psf
What it means
How much can it carry?
These are characteristic loads, before partial safety factors. Codes multiply them by 1.5 or so before a member is actually sized.
The math
How to convert psf to kN/m²
To convert pounds per square foot to kilonewtons per square meter, multiply by 0.0478803.
Example: 2.5 psf × 0.0478803 = 0.119701 kN/m².
In the other direction, 1 kN/m² = 20.8854 psf.
