Two types of cords are included with our PAAS-PAMP, Speaker Accessory.

The most accurate thing to do is to weigh the string and measure its length and calculate the mass per unit length. We may, over time, change our supply of this cord.

As of April 2, 2013, we did the measurements with what we are shipping:

Red braided cord
length mass
99 cm 1.22g
or 0.0123 g/cm

White stretchable cord, not stretched
59 cm 1.09 g
or 0.0185 g/cm
