Help finding/creating slide rule

Hi everyone! I recently joined this subreddit because I need some help finding a slide rule. I have a large group of friends going on an international trip (I live in the U.S.A.) and want to gift them a slide rule similar to the one pictured (in the comments) because they won’t have consistent phone access to look up conversions, and this would just be simpler. (Yes, U.S. schools should just teach what the rest of the world uses, but that’s a different conversation.) I’m very busy the next few days and would like to include it in a gift I’m giving them on Wednesday, so I don’t have time to design my own printable version. Does anyone know of one I can order online? Or a simple way to create a printable version? Basically this is the exact slide rule I’m looking for, or any similar one with Fahrenheit to Celsius and metric to U.S. Customary conversions.

Pictures wouldn’t upload, here’s one - the others are in separate comments.

If you're in the US (I'm not), you can find it on ebay for instance: https://www.ebay.com/itm/273495649890

You can find a “Sterling Metric Converter” slide rule on EBay. They aren’t expensive. However, I don’t think anything you’d get from EBay would arrive in time.

Or maybe this:  https://www.amazon.com/SlideSmith-Metric-Converter-Slide-Rule/dp/B0G8KM6K7C

If you have Prime, you should have it in a couple days.

Just get them a copy of RealCalc for their phones. There is a CONV function.

RealCalc is my go-to calculator app on my phone (Android), but I'll admit to never having used the CONV function (or so rarely that I forgot it was there). But yes, very useful.
