Hi Aitor, You'll have to enable 'on the fly' transformation in the Project Properties and then choose a CRS that projects everything to a metres-based CRS, e.g. UTM. Once you've done this the scale bar in your composer will be in metres.
By the way, the ArcGIS scale bar you mention isn't accurate. ArcGIS will happily allow you to choose km or metres for your scale bar units even when you are using geographic coordinates for your data frame but the length of the scale bar will be WRONG. You can test this by using the measuring tool to measure the length as indicated by the scale bar - you'll get a different length. Frank.

Hi, My issue is simple, when I make a map with composer, if I use a geographic coordinate reference system, I can't select meters like units for scale bar. For me it's fine, but my boss don't understand degrees like measuring unit in the maps, and then it's a problem for me. I know that with arcgis software you can choose the units so it´s possible to do that. Would be difficult to incorporate it into future versions or something like a pluging? Congratulations for the program, it's great!! Hugs.
