How to Convert Pounds per Square Inch to Hectopascals

To convert a measurement in pounds per square inch to a measurement in hectopascals, multiply the pressure by the following conversion ratio: 68.9475 hectopascals/pound per square inch.

Since one pound per square inch is equal to 68.9475 hectopascals, you can use this simple formula to convert:

hectopascals = pounds per square inch × 68.9475

The pressure in hectopascals is equal to the pressure in pounds per square inch multiplied by 68.9475.

For example, here's how to convert 5 pounds per square inch to hectopascals using the formula above.

hectopascals = (5 psi × 68.9475) = 344.7375 hPa

Pounds per square inch and hectopascals are both units used to measure pressure. Keep reading to learn more about each unit of measure.

What Are Pounds per Square Inch?

One pound per square inch is the pressure of equal to one pound-force per square inch.

The pound per square inch is a US customary and imperial unit of pressure. A pound per square inch is sometimes also referred to as a pound-force per square inch. Pounds per square inch can be abbreviated as psi; for example, 1 pound per square inch can be written as 1 psi.

PSI can be expressed using the formula:
1 psi = 1 lbf / in²

Pressure in pounds per square inch are equal to the pound-force divided by the area in square inches.

What Is a Hectopascal?

The hectopascal is equal to 100 pascals, which are defined as the pressure of one newton per square meter. The hectopascal is the internationally adopted unit used to measure atmospheric pressure.

The hectopascal is a multiple of the pascal, which is the SI derived unit for pressure. In the metric system, "hecto" is the prefix for 10². Hectopascals can be abbreviated as hPa; for example, 1 hectopascal can be written as 1 hPa.
