To convert from pascal (Pa) to kilopascal (kPa), you simply need to divide the pressure value by 1,000.
In the world of pressure measurement, the pascal is the base unit. However, because it is quite small, you will often see air pressure readings on a standard pressure gauge displayed in kilopascals (kPa) rather than pascals. This makes the numbers easier to read and record.
Note: If you are used to the imperial system, you might be looking for the pounds per square inch psi unit. While the formula below is strictly for metric units, understanding these prefixes is helpful before you attempt to convert from psi to kpa or other units.
Alternatively, you can multiply by 0.001:
Let's say you have a pressure reading of 5,000 pascal (Pa) and need to convert it.
Using the formula:
Therefore, 5,000 pascal (Pa) is equal to 5 kilopascal (kPa).
Here are some quick reference conversions from pascal (Pa) to kilopascal (kPa):

A pascal (Pa) is the standard unit of pressure in the International System of Units (SI). It is a derived unit, meaning other base units define it.
The primary pascal definition is one newton of force applied over an area of one square meter (1 Pa = 1 N/m2).
Because a single pascal represents a very small amount of pressure, it is most often seen in multiples.
The most common multiples are the kilopascal (kPa), equal to 1,000 pascals, and the megapascal (MPa), equal to 1,000,000 pascals.
These units are widely used in fields from weather forecasting to material science.
The pascal (Pa) unit is named in honor of Blaise Pascal, a key 17th-century French mathematician, physicist, and inventor.
His groundbreaking work on how fluids behave under pressure (known as hydrodynamics and hydrostatics) and his formulation of Pascal's Law were essential to our modern understanding of pressure.
To understand just how small a single pascal is, here are two real-world examples:
This shows why, for most everyday measurements (like tire pressure or weather), the larger kilopascal (kPa) is much more practical.
A kilopascal (kPa) is a metric unit of pressure that equals 1,000 pascals.
It is one of the most common units for measuring pressure worldwide, used in both scientific and everyday applications.
The base unit, the pascal (Pa), is named after the French polymath Blaise Pascal.
As part of the metric system (also known as the SI system), the kilopascal is widely used in scientific, engineering, and industrial fields due to its standardization and ease of calculation.
The kPa unit is used to measure pressure in many everyday and technical contexts. Common examples include:
For practical use, it's essential to understand how kPa converts to other common pressure units.
