Yoctojoules per kelvin to femtojoules per kelvin converter

Formula

Worked example

Convert 1 yJ/K to fJ/K:

1 yJ/K ≈ 1e-9 fJ/K

Multiply your yJ/K value by the factor above. The calculator uses the full conversion factor before rounding the displayed answer.

What yoctojoules per kelvin measure

Yoctojoules per kelvin (yJ/K) represent heat capacity. One unit equals 10^-24 J/K. Heat capacity is energy change per temperature change for an entire object or system.

Reading the result in femtojoules per kelvin

Femtojoules per kelvin (fJ/K) represent heat capacity. One unit equals 10^-15 J/K. Heat capacity is energy change per temperature change for an entire object or system.

Where this conversion helps

Convert a system heat capacity between energy-prefix scales. Specific heat capacity additionally divides by mass. A kelvin temperature difference has the same size as a Celsius degree difference.

How the scale changes

The input unit has a factor of 1e-24 J/K; the output unit has a factor of 1e-15 J/K. Multiply the entered number by the input factor, then divide by the output factor. The physical quantity stays the same while its numerical representation changes.

Reading very small or large results

Scientific notation keeps very small and large values readable: 2.5e-6 means 0.0000025. The converter calculates with 50 significant digits internally and displays up to 10. Exact unit definitions do not remove uncertainty from the original measurement.
