J/(g·K)toJ/(kg·°C)

1 J/(g·K) equals 1000 J/(kg·°C). To convert, multiply the value in joules per gram-kelvin by 1000.

1 J/(g·K) = 1000 J/(kg·°C). For any value, multiply by 1000.

Divide by the same factor — or equivalently, multiply by 0.001. So 1 J/(kg·°C) = 0.001 J/(g·K).

Specific-heat-capacity conversions between J/(g·K) and J/(kg·°C) are routine in thermal engineering, heat-balance work, HVAC design, metallurgy, chemical engineering and materials science. J/(kg·K) and kJ/(kg·K) are the SI standards; cal/(g·°C) is the classic thermochemical convention; BTU/(lb·°F) dominates US process and ASHRAE datasheets. All conversions use fixed multiplicative factors — this category does NOT look up the Cp value of any specific material (water, air, steam, etc.), does NOT perform heat-duty calculations (Q = m·Cp·ΔT), and does NOT convert lumped thermal capacity (J/K) to specific heat capacity (J/(kg·K)) without mass. Temperature units in the denominator represent temperature intervals, not absolute temperatures — a 1 °C interval equals a 1 K interval.

The factor shown is precise to at least 7 significant figures. For most process-engineering work this is far better than instrument accuracy. For metrology or trade applications, refer to the relevant national standard (NIST, BIPM, ISO 80000).
