Poundal

What is a poundal?

The poundal (pdl) is the FPS absolute unit of force; its mass-equivalent on this scale is about 0.0141 kg.

Origin of the poundal

Defined in the foot-pound-second absolute system in the late 19th century.

Where it is used

Early 20th-century physics and engineering.

When and where it was developed

Introduced in the absolute FPS system as an alternative to gravitational units.

Metric / SI

Attogram

What is a attogram?

An attogram (ag) equals 10^-21 kilogram.

Origin of the attogram

From the SI prefix 'atto-' (from Danish 'atten', eighteen).

Where it is used

Frontier nanoscience and single-molecule mass detection.

When and where it was developed

The atto- prefix was adopted by the CGPM in 1975.

Poundal to Attogram conversion formula

The relationship between poundals and attograms:

1 pdl = 1.408672e+19 ag
1 ag = 7.098885e-20 pdl

To convert poundals to attograms, multiply the value in poundals by 1.408672e+19. To reverse, multiply attograms by 7.098885e-20.

Step-by-step: convert poundals to attograms

  1. Write down the value in poundals (pdl).
  2. Multiply that value by the factor 1.408672e+19.
  3. The product is the equivalent value in attograms (ag).
  4. To reverse, multiply the attogram value by 7.098885e-20.

Worked examples

Example 1 — Convert 1 pdl to ag:
1 × 1.408672e+19 = 1.408672e+19 ag

Example 2 — Convert 100 pdl to ag:
100 × 1.408672e+19 = 1.408672e+21 ag

Real-world example — Small-scale to atomic-scale

One poundal equals 10 million attograms — useful for physics curricula that relate everyday measurements to atomic and optical scales.

1 pdl × 1.408672e+19 = 1.408672e+19 ag

Real-world example — Centimeter to wavelength scale

One poundal equals 10 million attograms. Physics curricula use this kind of conversion to relate everyday measurements to atomic and optical scales.

1 pdl × 1.408672e+19 = 1.408672e+19 ag
