convert into mm 5/8 6/8 11/16

Is it possible to convert into mm These Razor sizes 5/8 6/8 11/16 and also saw this on Amazon7 Straight (cut throat) Razors Titanium Finish in a Presentation Case plus Personalised Engraved Plaque (if required). 100% Money Back Guarantee: Amazon.co.uk: Health & Beauty what do others think? don't worry have been warned about the cheap stuff but the box looks nice

I don't know if it is the same manufacturer, however, if these are anything like the 'titanium' razors I bought of ebay (before I found SRP) RUN AWAY - they are rubbish.
Just my $0.02

Those razors are almost certainly junk.

1 inch = 25.4mm so to concert 5/8 of an inch to mm (5*25.4)/8= 15.875mm

home that helps

EDIT: if you type

Code:

---

5/8 inches to mm

into Google it will give you the result

The razors are Grab, if you wana buy for the box, i think there a cheaper solutions.
A bit homemaking and you have a box like that total cost i think one third of the price that the entire set costs( take a old sigarbox )
