dyne second to pound force second
Convert dyne second (dyn·s) to pound force second (lbf·s). Use an editable impulse converter, conversion formula, and reference table.
1 dyn·s = 0.000002248089431 lbf·s
Conversion formula
One dyne second equals 0.000002248089431 pound force second. Multiply your value in dyne second by this factor to get pound force second. For the reverse conversion, divide by the same factor.
Worked example
To convert 5 dyne second:5 × 0.000002248089431 = 0.00001124044715 lbf·s

About these measurements
Impulse is force integrated over time.
The base reference used here is the newton second. One dyne second is 0.00001 base units; one pound force second is 4.448221615 base units.
Important distinctions
Compound units must match the quantity and dimension. Temperature intervals use size factors rather than temperature offsets. Calorie and BTU entries use the explicit definitions shown.
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 dyn·s to lbf·s?
Multiply the quantity in dyn·s by 0.000002248089431. You can also type the value into the converter above.
Can I reverse the conversion?
Yes. Use the swap button or open the pound force second to dyne second converter.
