1 pascal (Pa) is equivalent to approximately 0.10197 kilograms-force per square meter (kgf/m²). Because pascal is a unit of pressure and kilogram (kg) is a unit of mass, direct conversion needs context on the area or force involved.
The pascal measures pressure, which is force per unit area (N/m²), while kilogram measures mass. To convert pascal to kilogram-force per square meter, we use the gravitational acceleration to relate newtons to kilograms-force. This conversion shows how much force a pressure of 1 pascal exerts over 1 square meter in terms of kilograms-force.

Conversion Formula
The pascal is a unit of pressure, defined as one newton per square meter (N/m²). Kilogram is a unit of mass, but when converting pressure to a force equivalent in kilograms-force per square meter, the force in newtons is divided by the standard gravity (9.80665 m/s²) to get the force in kilograms-force.
Formula:
kgf/m² = Pa ÷ 9.80665
This works because 1 newton equals the force needed to accelerate 1 kg at 1 m/s², but weight (force due to gravity) uses 9.80665 m/s² acceleration. So, dividing by gravity converts newtons of force to kilograms-force.
Example:
Convert 1 Pa to kgf/m²:
- 1 Pa = 1 N/m²
- 1 N = mass × gravity = mass × 9.80665 m/s²
- Therefore, mass (kgf) = force (N) ÷ gravity (9.80665 m/s²)
- 1 Pa = 1 N/m² = 1 ÷ 9.80665 ≈ 0.10197 kgf/m²
Conversion Example
- 5 Pa to kgf/m²:
- 5 Pa = 5 N/m²
- Force in kgf = 5 ÷ 9.80665 ≈ 0.5099 kgf/m²
- 10 Pa to kgf/m²:
- 10 Pa = 10 N/m²
- 10 ÷ 9.80665 ≈ 1.0197 kgf/m²
- 15.5 Pa to kgf/m²:
- 15.5 ÷ 9.80665 ≈ 1.5806 kgf/m²
- 0.75 Pa to kgf/m²:
- 0.75 ÷ 9.80665 ≈ 0.0765 kgf/m²
- 20 Pa to kgf/m²:
- 20 ÷ 9.80665 ≈ 2.0394 kgf/m²

Conversion Definitions
Pascal (Pa): A pascal is a unit of pressure in the International System of Units, equivalent to one newton per square meter (N/m²). It measures force applied per unit area, commonly used in physics and engineering to quantify pressure, stress, and tensile forces on materials.
Kilogram (kg): The kilogram is the base unit of mass in the International System of Units. It represents the mass of a specified international prototype. Kilograms are used worldwide for measuring mass or weight and serve as a standard for scientific and everyday measurements.
Conversion FAQs
Why can’t I convert pascal directly to kilograms without considering area or force?
Because pascal measures pressure (force per area), and kilogram measures mass, converting between them requires information about the force or the area involved. Without knowing the area over which pressure applies or the force acting, direct conversion isn’t meaningful.
Is the conversion from pascal to kilograms affected by location or gravity?
Yes, since kilograms-force depends on gravitational acceleration, which varies slightly over the Earth. The standard gravity used for conversion is 9.80665 m/s², but local gravity changes can affect precise calculations, although the difference is usually small.
What does kilograms-force per square meter mean compared to pascal?
Kilograms-force per square meter expresses pressure in terms of the weight force of kilograms over an area, while pascal uses newtons per square meter. Both measure pressure, but kgf/m² relates more directly to everyday weight measurements.
Can I use this conversion for gases and liquids pressure measurements?
Yes, pressure units apply to gases and liquids. However, when converting pascals to kilograms-force per square meter, ensure that the application context suits force per area, like measuring pressure on surfaces or containers.
How precise is the conversion from pascal to kgf/m²?
The conversion is precise when using the standard gravity constant and accurate pascal values. Minor variations in gravity or measurement accuracy can cause slight differences, but for most practical purposes, it’s exact enough.
