In 1 poundals there are 13,825.5 dynes. Meanwhile in 1 dynes there are 0.0000723301 poundals. Keep reading to learn more about each unit of measure and how they are calculated. Or just use the Dynes to Poundals calculator above to convert any number.

To convert poundals (pdl) to dynes (dyn), use the link through newtons (N).
That gives the key conversion:
Conversion formula (poundal to dyne):
Reverse formula (dyne to poundal):
Example: 5 pdl = 5 × 13,825.495 = 69,127.475 dyn.
A poundal (pdl) is a unit of force from the foot-pound-second (FPS) system. It’s the force needed to accelerate a 1-pound mass at 1 foot per second squared (1 ft/s²). You may see it in older physics texts and engineering notes.
A dyne (dyn) is a unit of force in the centimeter-gram-second (CGS) system. It’s the force needed to accelerate a 1-gram mass at 1 centimeter per second squared (1 cm/s²). Dynes are common in older mechanics problems and some lab work.
Use this conversion factor:
To convert poundals to dynes, multiply by 13,825.495:
The standard formula is:
If you need the reverse conversion:
The poundal is based on feet, pounds, and seconds. The dyne is based on centimeters, grams, and seconds. The conversion comes from changing feet to centimeters and pounds (mass) to grams, while keeping the same acceleration structure in each system.
A poundal is a unit of force. It’s tied to a 1-pound mass and a 1 ft/s² acceleration, but the result is still force.
No. The SI unit of force is the newton (N). The dyne is a CGS unit. You may still see dynes in older references or in some niche fields.
Multiply by the conversion factor:
Here are helpful reference points:
These values help when you need to move between CGS, FPS, and SI units.
A few errors come up often:
Round based on how precise your input is. If your poundal value has two decimal places, don’t report dynes with ten. For most work, 3 to 6 significant figures is enough unless your lab or spec calls for more.
The Calculate Box tool to convert poundals to dynes uses the open source script Convert.js to convert units of measurement. To use this tool, simply type a poundals value in the box and have it instantly converted to dynes.
