From UK to US for an airmal letter, no.

I don't think you would need one from US to UK either but i'm not 100% sure.

I don't think i've ever had a customs label either way for my UK to US requests

When ordering something from the US to UK, it was possible that an item over £18 in value could be subject to customs checks, but not always.

I would guess it's the same from US to UK but this can change quite often.

You can weigh your return item in ounces and then use an online conversion calculator for weight to get a weight in grams.

Then, go to http://www.royal-mail.com/pricefinder which will assist you in calculating the cost of your item.

I send out 6x4s so can't help any more than that

There are several celebrities residing in the UK that I would love to write to. Problem being that I live in the US. I've read the sticky thread here about international postage and have even attempted to figure out the Royal Mail's website. But the issue I have is that, since I do live in the US, I'm not that familiar with the metric system for weights.

Can anyone in the UK offer some advice on how much postage you use to send a SASE, LOR and let's say one 8x10 photo to the US?

Once I get that sorted, I'll try to figure out how to get some UK postage.

Thanks in advance.
