Skate Sharpening - ROH Questions

[leonzhu 7]

Hi EQMs/Sharpening pros on this board,

I've always played in the UK and CONUS, so I only know my ROHs in inches.

However i've now moved back to singapore and the guy asks me if i want it done in 9, 11, 13 or 15? Is this in mm or some arbitrary measurement?

Does anyone have a handy conversion chart?

The conversion factor is 25.4

3/8" x 25.4 = 9.525 mm

1/2" x 25.4 = 12.7 mm

3/4" x 25.4 = 19.05 mm

....

The T-blade conversion only works if the blades are the same width as a standard steel blade. Are they?

I measured some blades that I have. The RBK/CCM ones are 2.8mm wide. Bauer LS2 are 3.0mm wide. T-Blades are 3.0mm wide.

And it's weird that the T-Blade chart doesn't correspond to the actual value in mm's. Maybe their values average the grip you get between bauer and CCM/RBK for the same ROH?
