Converting usa measurements to international measurements for inventory

Okay, so this may be a funny question and I feel like I should know, but I do not.

I’ve never added in international measurements before. I’ve always just put in USA measurements. I’m expanding on shipping to international, so it is much needed information.

This would be for all types of listings…jewelry, hosiery, ornaments…everything.

Say I have a necklace that has a length of 17 inches….would I give it an mm measurement or give it a cm measurement and/or does it depend on the country as to which one to use?

And what if I have a necklace that measures 17.5 inches rather than 17 inches… this is where it seems to get tricky.

Thank you,

Sharon

1 inch = 2.54 cm or 25.4 mm. Those who live under the Metric System will understand either cm or mm. So, take your inch measurements and multiply by 2.54 to convert to cm or multiply by 25.4 to convert to mm.

Practically speaking, you could also round those conversion multipliers to 2.5 or 25 and the resulting metric number will probably suffice.

17.5 inches would convert to 43.75 (rounded) or 44.45 cm (unrounded). Calling it 44 cm (or 440 mm) would be fine.

Did you catch that the mm result is 10x cm?

No, I did not catch 10x cm until you mentioned it. Thank you very much, Tom :)

Hello,

I am from Australia – and when I was listing on here – I did both inches and mm/cm for most items – just to cover all bases because of the international customers. We use mm and cm in Australia and the UK – and I found it difficult for the US system – just used a conversion program when I was listing to put in the different measurements.

I never knew that Australia AND the UK use both cm and mm. Knowing this really helps. :)

This (and many others) conversion of measurement units site is very [URL removed]

I use cm (as in most European countries painting’s dimensions in mm would look unnatural) and inches (sometimes in both [URL removed] e.g. 3.5 and 3 35/64 inch).

So, for Your necklace, personally, I would write 17.5 inch and ~ 44,5 cm.

Depending on how large the item is, I usually round to integer numbers or to one digit after comma/period, using the general mathematical rule for rounding.

Thank you. You all have been very helpful with this.

So, I will include both cm and mm then.

I really appreciate the help. This will be a bit more time consuming than just using good old fashioned USA measurements, but I figure if I’m going to be shipping international….I need to go all the way and put my best foot forward!!

Here is a listing where I added cm and mm measurements. Does it look okay?
