Suppose I wish to use Boltzmann constant in calculations, and I queried it from Wolfram Alpha:

enter image description here

Now, how to take any of selected values?

If I copy paste

enter image description here

I get garbage. How to perform?

  • $\begingroup$ Hover the mouse over the value of choice, the little window drops down, click on the orange A in that which has alt text saying "copyable plain text", click on that and scrape and paste elsewhere $\endgroup$ – Bill Feb 22 '15 at 18:22

Better to use the free-form input interface rather than the Wolfram | Alpha interface for this kind of thing.

boltzmann

UnitConvert[%]
Quantity[1.38065*10^-23, ("Kilograms" ("Meters")^2)/("Kelvins" ("Seconds")^2)]
