Dear reader,
I thought I was getting the hang of converting units but came across a thermal conductivity value and the unit was given in: BTU/hrftR I assume the 'R' means 'Rankine'. I want to convert to the SI unit for Thermal Conductivity: W/(m·K) Any ideas? Or if you know where to find the Thermal Conductivity of refrigerant R134a at 60.29degs C please let me know ;). Thank you

Excellent Thank you very much, have saved that Common conversion factors pdf as well.
Thermal Conductivity was the last piece to this small puzzle and couldn't do anything til I found that.

Can you Convert these units?
No worries  note: often all you need to do is google the units you want to convert ;)

I copied and pasted your format into the searchbar  though google has learned the sorts of results I like so maybe that accounts for it. I often do that when I'm not sure what's intended.
The format in post #2 was copied and pasted from the Common Conversions PDF :)

try going to wolfram alpha I put in your question and it spits back a reasonable answer and a graph enjoy it is a useful tool. Also as a low cost app on Ipad and android chris
