psf to Pa Online Converter – Pounds/Foot2 to Pascals

This online converter allows you to easily convert between pounds per square foot (psf) and pascals (Pa). It is particularly useful for engineers, architects, and anyone involved in construction or structural analysis where pressure and force per unit area need to be converted between imperial and metric units. The tool works both ways, enabling you to convert from psf to Pa and vice versa.

How to Use the Calculator

To use this converter, simply enter the value in pounds per square foot (psf) in the input field labeled “Pounds per Square Foot (psf)”. The corresponding value in pascals (Pa) will be automatically calculated and displayed in the output field. If you need to convert pascals to pounds per square foot, input the value in the “Pascals (Pa)” field, and the equivalent value in pounds per square foot will be shown.

Formula Used

The formula used for converting pounds per square foot (psf) to pascals (Pa) is:

Pascals (Pa) = Pounds per Square Foot (psf) × 47.88025898

For the reverse conversion (Pa to psf), divide the value in pascals by 47.88025898.

Precalculated Values

Here are some commonly converted real-world values:

• 1 psf = 47.8803 Pa (roughly the pressure exerted by a light object on a table)
• 10 psf = 478.803 Pa (approximately the pressure of a book on a small surface)
• 50 psf = 2394.01 Pa (equivalent to the pressure exerted by a large piece of furniture)
• 100 psf = 4788.03 Pa (similar to the pressure of a person standing on a surface)
• 500 psf = 23940.13 Pa (pressure close to that exerted by a heavy object or machinery)
• 1000 psf = 47880.26 Pa (pressure akin to that of a vehicle on the ground)
• 5000 psf = 239401.29 Pa (common in industrial settings for heavy equipment pressure)

History and Interesting Facts

Pounds per square foot (psf) is a unit commonly used in the United States and other countries that follow the imperial system to measure pressure or force per unit area. It is especially prevalent in construction, where it’s important to understand the pressure exerted by various loads on surfaces.

Pascals (Pa), on the other hand, are the SI unit for pressure, widely used across the world in scientific and engineering applications. Named after Blaise Pascal, a French mathematician and physicist, this unit represents the pressure of one newton per square meter. Converting between these two units is crucial when working in international projects or when translating imperial measurements to the metric system.
