What is the unit of measurement for gravitational waves?

Now that we have found einsteins gravitational waves; I am writing a bit of science fiction which is centered around space-fold/warp technology. I am curious, now that Einsteins gravitational waves have been proven; what is the unit of measurement by which they are measured? Also are these gravitational waves measurable in the electro-magnetic wave-length? I ask, because by this measure, wouldn't "warp" drives use wave-length to measure jumps?

The typical unit is strain h, which is dimensionless. It's the change in distance over the total distance (h=∆L/L). This is a very small number, as you might imagine, since gravitational waves are extremely hard to detect. For LIGO, h was 1 x 10^-21.

You may also want to consider the gravitational wave frequency, which was in the 10s to several 100s of Hz for LIGO. For other experiments, such as pulsar timing arrays, h is expected to be many orders of magnitude larger, but at frequencies much, much lower, so LIGO can't detect them. The frequencies are analogous to electromagnetic frequencies since gravitational waves propagate at the speed of light (i.e., the wavelengths are defined the same way).
