kJ/(kg·K)toJ/(g·K)

Convert kilojoules per kilogram-kelvin (kJ/(kg·K)) to joules per gram-kelvin (J/(g·K)).

Factor1 kJ/(kg·K) = 1 J/(g·K)

Converter

kJ/(kg·K)

Accepts numbers or expressions, e.g. 150 + 14.7

Result
4.184J/(g·K)

Rendered to 6 significant figures.

Formula

Formula
J/(g·K) = kJ/(kg·K) × 1

Multiply any value in kilojoules per kilogram-kelvin by 1 to obtain the value in joules per gram-kelvin.

Worked example

Convert 4.184 kJ/(kg·K) to J/(g·K).

  1. 01Start with 4.184 kJ/(kg·K).
  2. 02Multiply by the conversion factor: 4.184 × 1 = 4.184 J/(g·K).
Result4.184 kJ/(kg·K) = 4.184 J/(g·K)

FAQ

What is the conversion factor from kJ/(kg·K) to J/(g·K)?
1 kJ/(kg·K) equals 1 J/(g·K). To convert, multiply the value in kilojoules per kilogram-kelvin by 1.
How do I convert 1 kJ/(kg·K) to J/(g·K)?
1 kJ/(kg·K) = 1 J/(g·K). For any value, multiply by 1.
How do I convert J/(g·K) back to kJ/(kg·K)?
Divide by the same factor — or equivalently, multiply by 1. So 1 J/(g·K) = 1 kJ/(kg·K).
When would I need to convert kilojoule per kilogram-kelvin to joule per gram-kelvin?
Specific-heat-capacity conversions between kJ/(kg·K) and J/(g·K) 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.
Is the conversion exact?
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).
