  We aim to use the a new and improved version of AKARI all sky survey
catalogue of far-infrared sources to recalibrate the formula to derive the
total infrared luminosity. We cross-match the faint source catalogue (FSC) of
IRAS with the new AKARI-FIS and obtained a sample of 2430 objects. Then we
calculate the total infrared (TIR) luminosity $L_{\textrm{TIR}}$ from the
Sanders at al. (1996) formula and compare it with total infrared luminosity
from AKARI FIS bands to obtain new coefficients for the general relation to
convert FIR luminosity from AKARI bands to the TIR luminosity.
