units of variables?

[Tonig00]

Hello
Just a curiosity of this new version:
When I tried to convert m/s into Km/h like: 1_m/s►1_km/h gives an error (“bad argument type” on the calculator, “Syntax error” on the computer with Windows)

When done with CONVERT it works perfectly.

With other units the operator ► works nice

I do not know if this is a problem with my calculator and, anyway is not really important.

Thanks
