Conversion factors from Jy2/sr to μKCMB.

wavelength (μm) Instrument Jy2/sr to μK

100 IRAS 9.59 × 1022
160 Spitzer/MIPS 3.12 × 1011
250 Herschel/SPIRE 1.34 × 103

350 Herschel/SPIRE 2.78 × 10-1
350 Planck/HFI 2.00 × 10-1

500 Herschel/SPIRE 7.45 × 10-4
550 Planck/HFI 2.94 × 10-4

850 Planck/HFI 1.20 × 10-5

1380 SPT 4.39 × 10-6
1380 Planck/HFI 4.32 × 10-6

2000 SPT 6.10 × 10-6
2097 Planck/HFI 7.31 × 10-6

Notes. One should multiply the power spectrum in Jy2/sr (with the convention νIν =  cst.) by the coefficient to get μK.
