How to Convert kPa to Attopascal?
Converting from kPa to Attopascal is a straightforward process. Follow these steps to ensure accurate conversions from kilopascal to attopascal:
- Select the Kilopascal Value: Start by determining the kilopascal (kPa) value you want to convert into attopascal (Attopascal). This is your starting point.
- Multiply by the Conversion Factor: To calculate kilopascal to equivalent attopascal amount, multiply the selected kPa value by 1e+21.
- Illustration of Multiplication:
- 1 kPa = 1e+21 Attopascal
- 10 kPa = 1e+22 Attopascal
- 100 kPa = 1e+23 Attopascal
- Find the Conversion Result: The result of this multiplication is your converted value in attopascal unit. This represents the same pressure but in a different unit.
- Save Your Attopascal Value: After converting, remember to save the result. This value represents the pressure you initially measured, now expressed in attopascals.
- Alternative Method – Division: If you prefer not to multiply, you can achieve the same conversion by dividing the kilopascal value by 1e-21. This alternative method also gives you the correct pressure in attopascals.
- Illustration of Division:
- Attopascal = kpa ÷ 1e-21
What is Pressure?
Pressure is the force applied perpendicular to a surface per unit area: P = F / A. The SI unit is the pascal (Pa), equal to one newton per square metre (1 Pa = 1 N/m²). Practical applications use larger units: the bar (1 bar = 100,000 Pa, close to standard atmospheric pressure), atmosphere (atm) (1 atm = 101,325 Pa), and psi (pounds per square inch, used in the US for tire and gas pressures). Blood pressure is measured in mmHg (millimetres of mercury), also called torr.
What is Kilopascal?
The kilopascal (symbol: kPa) is an SI-derived unit of pressure equal to one thousand (103) pascals. It is one of the most widely used pressure units in engineering, meteorology, automotive systems, construction, and scientific research. The kilopascal provides a practical scale for measuring atmospheric pressure, tire pressure, and fluid pressure. It uses the SI prefix kilo, representing a factor of one thousand.
One kilopascal is equal to 1,000 pascals, 0.01 bar, 0.001 megapascal, 0.145038 psi, and 0.00986923 standard atmosphere. The kilopascal is the preferred SI unit for many everyday and industrial pressure measurements.
What is Attopascal?
The attopascal (symbol: aPa) is an SI-derived unit of pressure equal to one quintillionth (10-18) of a pascal. It is an extremely small pressure unit used mainly in theoretical physics, nanotechnology, and scientific research involving ultra-low pressure measurements. The attopascal uses the SI prefix atto, representing a factor of 10-18.
One attopascal is equal to 0.000000000000000001 pascal, 0.001 femtopascal, 0.000000001 nanopascal, 1×10-23 bar, and 9.86923×10-24 standard atmosphere. Although rarely used outside research, the attopascal is part of the complete SI pressure scale.

Kilopascal to Attopascal Examples
Example 1:
Convert 0.4 Kilopascal pressure to Attopascal unit.
Solution:
We know that one Kilopascal is equivalent to 1e+21 Attopascal.
Therefore,
0.4 kPa = 0.4 x 1e+21 Attopascal.
0.4 kPa = 4e+20 Attopascal.
Hence, 0.4 Kilopascal is approximately equal to 4e+20 Attopascal.
Example 2:
Convert 9 Kilopascal pressure to Attopascal unit.
Solution:
We know that one Kilopascal is equivalent to 1e+21 Attopascal.
Therefore,
9 kPa = 9 x 1e+21 Attopascal.
9 kPa = 9e+21 Attopascal.
Hence, 9 Kilopascal is approximately equal to 9e+21 Attopascal.
