Metric should be included

[amandasaurus]

The spec should include metric units. What the hell is an inch?

[gromain]

Agreed 100%.

An inch is an archaic unit of measurement used by Liberia, Myanmar, and some country north of Cuba: http://www.nerdylorrin.net/jerry/postages/MapOfCountriesNotMetric-800px.jpg

An inch is used because the "official" stickers were created using inches and a satisfactory conversion to metric has not yet been found.

UK is also found of imperial units, alongside the offical metric units.

Well, 2 inches is 50.8mm .
I guess, we could close it to 50mm for the sake of practicality, or 51mm.

[terinjokes]

Yes, even in the United States we can convert to centimeters. The issue is in the rounding which is why I said "and a satisfactory conversion to metric has not yet been found."

[gromain]

I didn't mean no disrespect!

It's just that from my point of view, either we round it to 50mm or 51mm.
I feel that smaller should not be a problem (less than 0.5mm on each side
from the imperial standard) as the sticking precision will be in the same
range.
