Unit size (scale) from XSI to Sandbox

[Feersum]

Am I right in assuming 1 unit size in XSI equals 1 meter in Sandbox?

(I've noticed there is no way to change the unit scale in XSI like you can in MAX)

I am unsure what the official ratio is, but many people on the crymod forums are working to 1 XSI unit = 1 meter in Crysis/SB2
