Kalorimetrning idishi ham pitradan ajralgan issiqlikning bir qismini yutadi. Demak, kalorimetrning issiqlik sig’imi quyidagiga teng bo’ladi
C_K=C₂⋅m_K (V)

Shunday qilib, kalorimetr idishining suv ekvivalenti m_K hisoblashlarda hisobga olinadi. (III) formula bilan hisoblangan yutilgan issiqlikning miqdori ancha aniqroq hisoblanadi
ΔQ₂=c₂⋅(m₂+m_K) ⋅(ϑ_M -ϑ₂)

va uni hisobga olgan holdagi (IV) formula quyidagi ko’rinishga keladi:


1 2
𝑐 = 𝑐 ∙ ^{(𝑚2+𝑚𝑘)(𝜗𝑀−𝜗2)} (VII). 1 1 1
