Thermal Conductivity:

Material: 

Area:   m2 Temperature at one end:   K
 
Length:   m  Temperature at other end:   K


Specific Heat:

Material: 

Mass:  kg

Begin temperature:  K End temperature:  K


Blackbody (Options with asterisks are untested):

Use wavelength: Start:  m Stop:  m
Use frequency: Start:  Hz Stop:  Hz
*** Use % wavelength band

Temperature:  K Area:  m2 Emissivity: 

Solid Angle:   ster(adians)

Hint: You can enter numbers in scientific notation using the letter E, as in "1e12" and "3.24E-4"

Conductivity and specific heat calculations use NIST cryogenics data; blackbody calculations use Planck's Equation. Code for each is by Shlomo Katz and Jeff Klein.
