On quick note, **1 PSI = 144 PSF**, use this **PSI to PSF **conversion tool that allows you to** easily convert** between these two pressure units.

**PSI** (Pounds per Square Inch) and **PSF** (Pounds per Square Foot) are both units used to measure **pressure**, but they differ in the area they represent. **PSI** measures the pressure exerted on a **1-square-inch** area, while **PSF** measures the pressure exerted on a **1-square-foot** area.

For example, let’s consider the following sample conversions:

**1 PSI = 144 PSF**– This means that a pressure of**1 pound per square inch**is equivalent to**144 pounds per square foot**.**10 PSI = 1,440 PSF**– In this case, a pressure of**10 pounds per square inch**is equivalent to**1,440 pounds per square foot**.**50 PSI = 7,200 PSF**– A pressure of**50 pounds per square inch**is equal to**7,200 pounds per square foot**.

PSI | PSF | Conversion Equation |
---|---|---|

10 psi to psf | 1,440 | PSF = PSI × 144 |

25 psi to psf | 3,600 | PSF = PSI × 144 |

30 psi to psf | 4,320 | PSF = PSI × 144 |

100 psi to psf | 14,400 | PSF = PSI × 144 |

250 psi to psf | 36,000 | PSF = PSI × 144 |

1,000 psi to psf | 144,000 | PSF = PSI × 144 |

1,500 psi to psf | 216,000 | PSF = PSI × 144 |

2,000 psi to psf | 288,000 | PSF = PSI × 144 |

The conversion equation used in the table is:

**PSF = PSI × 144**

Where:

**PSF**is the pressure in pounds per square foot**PSI**is the pressure in pounds per square inch

This equation is used to convert the given PSI values to their corresponding PSF values.

## PSI to PSF Conversion Formula

The formula to convert **PSI** to **PSF** is:

**PSF = PSI × 144**

Let’s walk through a few examples using this formula:

**Example 1: Converting 5 PSI to PSF****PSF = PSI × 144****PSF = 5 × 144****PSF = 720**- Therefore,
**5 PSI**is equivalent to**720 PSF**.

**Example 2: Converting 20 PSI to PSF****PSF = PSI × 144****PSF = 20 × 144****PSF = 2,880**- Therefore,
**20 PSI**is equivalent to**2,880 PSF**.

**Example 3: Converting 100 PSI to PSF****PSF = PSI × 144****PSF = 100 × 144****PSF = 14,400**- Therefore,
**100 PSI**is equivalent to**14,400 PSF**.

The key thing to remember is that the conversion factor between **PSI** and **PSF** is always **144**.

This is because there are **144 square inches** in a square foot (**12 inches × 12 inches = 144 square inches**).

## Is PSF the Same as PSI?

No, **PSF** (Pounds per Square Foot) and **PSI** (Pounds per Square Inch) are not the same. They are both units used to measure **pressure**, but they differ in the area they represent.

**PSI** measures the pressure exerted on a **1-square-inch** area, while **PSF** measures the pressure exerted on a **1-square-foot** area.

This means that the values for the same amount of pressure can differ significantly depending on whether you’re using **PSI** or **PSF**.

For example, a pressure of **10 PSI** is equivalent to **1,440 PSF** (**10 PSI × 144 = 1,440 PSF**). This highlights the importance of using the correct pressure unit when working on various projects or calculations.

## How Do You Calculate Pressure in PSF?

To calculate pressure in **pounds per square foot (PSF)**, you can use the following formula:

**PSF = Force / Area**

Where:

**PSF**is the pressure in pounds per square foot**Force**is the force applied (in pounds)**Area**is the surface area (in square feet)

Suppose you have a force of **1,000 pounds** being applied to a surface with an area of **50 square feet**. To calculate the pressure in **PSF**, you would use the following steps:

**Identify the given values:**- Force =
**1,000 pounds** - Area =
**50 square feet**

- Force =
**Apply the formula:****PSF = Force / Area****PSF = 1,000 pounds / 50 square feet****PSF = 20 pounds per square foot**

The pressure exerted on the **50-square-foot** surface with a force of **1,000 pounds** is **20 PSF**.

## What is a PSF Equal To?

**PSF** (Pounds per Square Foot) is a unit of pressure that is equal to the force of **1 pound** applied evenly over an area of **1 square foot**.

Specifically, **1 PSF** is equivalent to:

**1 pound of force per square foot****4.88 kilograms per square meter (kg/m²)****0.048 kilonewtons per square meter (kN/m²)**

The conversion factors are as follows:

**1 PSF = 1 pound per square foot****1 PSF = 4.88 kg/m²****1 PSF = 0.048 kN/m²**

These conversion factors allow you to easily convert between **PSF** and other pressure units, such as **kilograms per square meter (kg/m²)** or **kilonewtons per square meter (kN/m²)**, depending on the requirements of your application.

## How Much is 2160 PSF in **PSI**?

To convert **2160 pounds per square foot (PSF)** to **pounds per square inch (PSI)**, we can use the following formula:

**PSI = PSF / 144**

Where:

**PSI**is the pressure in pounds per square inch**PSF**is the pressure in pounds per square foot

Plugging in the values:

**PSI = 2160 PSF / 144****PSI = 15 PSI**

**2160 pounds per square foot (PSF)** is equivalent to **15 pounds per square inch (PSI)**.

The reason for dividing by **144** is that there are **144 square inches** in a square foot (**12 inches × 12 inches = 144 square inches**).

This conversion factor allows us to convert the pressure from a **1-square-foot** area to a **1-square-inch** area.
