femtopascal to attopascal

Convert femtopascal (fPa) to attopascal (aPa). Use an editable pressure converter, conversion formula, and reference table.

1,000

1 fPa = 1,000 aPa

Calculated in your browser

Conversion formula

aPa = fPa × 1,000

One femtopascal equals 1,000 attopascal. Multiply your value in femtopascal by this factor to get attopascal. For the reverse conversion, divide by the same factor.

Worked example

To convert 5 femtopascal:
5 × 1,000 = 5,000 aPa

About these measurements

Pressure is force per unit of area.

The base reference used here is the pascal. One femtopascal is 1e-15 base units; one attopascal is 1e-18 base units.

Important distinctions

Gauge and absolute pressures must not be mixed. This converts units without changing the reference pressure.

Precision

The converter uses stored conversion factors and floating-point arithmetic. Results display up to ten significant digits, switching to scientific notation for very small or large values. Keep the precision of your original measurement when reporting results.

Common questions

How do I convert fPa to aPa?

Multiply the quantity in fPa by 1,000. You can also type the value into the converter above.

Can I reverse the conversion?

Yes. Use the swap button or open the attopascal to femtopascal converter.
