sci.action-potential-speed Calculator
Calculates action potential conduction velocity along a nerve axon from axon diameter and myelination status. Myelinated axons conduct at 70–120 m/s; unmyelinated at 0.5–2 m/s — the squid giant axon (up to 1 mm diameter) achieves 25 m/s without myelin, enabling rapid escape reflexes.
Inputs
Axon Diameter Um
Distance across a circle through its centre. Always confirm units match the rest of the calculation.
Myelination Factor
Reference formula or conversion factor shown for context.
Temperature C
Thermal state of the substance. Check whether the formula needs Celsius, Fahrenheit, or Kelvin (K = °C + 273.15).
Results
conduction velocity (m/s)
Sample size or count used in the calculation.
type
The classification or type assigned based on the inputs.
at 37°C
The value at the specified point or condition.
Aα fibers (large motor)
Reference formula or conversion factor shown for context.
C fibers (unmyelinated pain)
The value at the specified point or condition.
Q10 factor
A dimensionless multiplier applied in the calculation.
