fabricjs works in pixels. There is a function: fabric.util.parseUnit() that can parse inches, mm, pixels, points.

    a = new fabric.Rect({ 
                top:0,
                left:0 ,
                fill: '#000',
                width: fabric.util.parseUnit('50mm'),
                height: fabric.util.parseUnit('50mm'),

            });
    b = new fabric.Rect({   
                top:0,
                left:200,   
                fill: '#000',
                width: fabric.util.parseUnit('1in'),
                height:  fabric.util.parseUnit('1in'),
            });
canvas.add(a, b);
