Reduce number of decimals in measure tool

Hi!

I would like to decrease the number of decimal digits shown when I use the measurment tool in ArcMap 10.1 SP1 Win7 64 bit. As of now it shows me six decimals! Two decimals would be more apporpriate...
I have searched high and low and start to think that changing the number of decimals is not doable. I hope someone out there can prove me wrong! ;)

Thanks in advance!
Regards,
Richard
