Units and numerical value on the ground motion

[YoungXu]

Dear sir,
I have three questions.
1. After I set the units, how can I embed it into the groundmotion?
2. I download the groundmotion data from this web(http://peer.berkeley.edu/smcat/index.html), but the accel data like this "-0.004524259" which is too small, how can I change it? The other examples show the accel data like this "-4.524259"
3. Upon the website, what is the accel data's default units?

1) use the -factor option wih the timeSeries.
2) in the -factor option
3) g in imperial units typically.
