Converting thermal conductivity from BTU/hr-ft-R to W/(m·K)

[recreated]

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/hr-ft-R 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 R-134a at 60.29degs C please let me know ;).

Thank you

1 W/(m·K) = 0.5778 Btu/(h·ft·R)

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.

No worries - note: often all you need to do is google the units you want to convert ;)

cheers, I did google it but not in the format you type it and got bad results,, Good thing is I know to use that format you have used. Funny, what ever way i type it in Google now it knows what I mean :D

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
