1 pascal is equal to approximately 0.10197 kilograms-force per square meter (kgf/m²). Since pascal measures pressure and kilogram (kg) measures mass, directly converting between them requires considering the area and gravitational acceleration.
Pressure in pascals (Pa) is force per unit area (N/m²), and force relates to mass via gravity. Thus, converting 1 Pa to kg needs defining how the pressure applies over an area to find equivalent mass causing that force.

Conversion Formula
The pascal (Pa) is a unit of pressure defined as one newton per square meter (N/m²). Kilogram (kg) is a unit of mass. To convert pressure to mass, the force causing that pressure must be considered over an area with gravity acting on the mass.
The formula to relate pressure to mass over 1 square meter is:
mass (kg) = pressure (Pa) / gravitational acceleration (m/s²)
Since 1 Pa = 1 N/m² and Force (N) = mass (kg) × gravity (9.80665 m/s²), rearranging:
- Force = Pressure × Area
- Mass = Force / gravity
- Assuming area = 1 m², mass = Pressure / 9.80665
Example:
1 Pa corresponds to mass: 1 / 9.80665 ≈ 0.10197 kg
Conversion Example
- Convert 5 Pa to kg:
- Multiply pressure by area (1 m²): 5 × 1 = 5 N
- Calculate mass: 5 N / 9.80665 m/s² = 0.5099 kg
- Convert 12.5 Pa to kg:
- Force = 12.5 N (over 1 m²)
- Mass = 12.5 / 9.80665 ≈ 1.2746 kg
- Convert 0.75 Pa to kg:
- Force = 0.75 N
- Mass = 0.75 / 9.80665 ≈ 0.0765 kg
- Convert 20 Pa to kg:
- Force = 20 N
- Mass = 20 / 9.80665 ≈ 2.039 kg
- Convert 3.2 Pa to kg:
- Force = 3.2 N
- Mass = 3.2 / 9.80665 ≈ 0.3263 kg

Conversion Definitions
Pascal (Pa): Pascal is a unit of pressure in the International System of Units, defined as one newton per square meter (N/m²). It quantifies force applied perpendicular to a surface area and is widely used in physics, engineering, and meteorology to measure pressure exerted by gases, liquids, or solids.
Kilogram (kg): Kilogram is the base unit of mass in the International System of Units. It represents the amount of matter in an object, defined by the Planck constant since 2019. The kilogram is used globally for measuring weight and mass in science, commerce, and daily life.
Conversion FAQs
Why can’t pascal be directly converted to kilogram without knowing the area?
Pascal measures pressure, which is force per unit area, while kilogram measures mass. To convert pressure into mass, you need to know the area over which the pressure acts, because force equals pressure multiplied by area. Without area, the conversion lacks context and cannot be done accurately.
How does Earth’s gravity influence the conversion from pascal to kg?
Gravity links force to mass by defining how much force a given mass exerts. Since pascal is force per square meter, converting to mass requires dividing force by gravitational acceleration (9.80665 m/s²). Variations in gravity would change the mass equivalent for the same pressure.
Is the conversion formula the same on other planets?
No, the formula depends on gravitational acceleration, which varies by planet. On planets with stronger or weaker gravity, the mass corresponding to a given pascal will change, because force = mass × gravity. The formula must use local gravity for accurate results.
Can I convert pascal to kilogram without considering area if pressure is uniform?
No, even if pressure is uniform, mass depends on force applied over an area. Pressure alone lacks information about total force or mass unless the area over which it acts is known. Uniform pressure only simplifies calculation if area is provided.
Why is the formula dividing pascal by 9.80665 to get kilograms?
Because 1 pascal equals 1 newton per square meter, and force in newtons equals mass times gravity. To find mass, force is divided by gravitational acceleration. Hence, mass (kg) = pressure (Pa) / gravity (m/s²). The number 9.80665 m/s² represents Earth’s average gravity.
