Size Modifiers for Computers?

[Pursuivant]

On another thread, a reasonable formula for SM based on mass for living creatures was:

Size = LN(Mass/250 lbs.). Setting the number to something more appropriate for a Size 0 machine (e.g., 500 lbs.) might get you in the ballpark.

If that seems too math-heavy, look at the description for the item. Something like a mini/wearable computer or smart phone is likely to be Size -7 to -6. A laptop-sized computer will be Size -5, desktop/personal Size -4 to -2 depending on form factor. A mini-frame is going to be -1 to 0, etc.
