Solve for
(unknown)

Fill the other three values.

Material preset (c)

Sets c automatically (you can still edit it).

Heat energy (Q)

Energy added (+) or removed (−).

Mass (m)

Mass of the material.

Specific heat (c)
J/(kg·°C)

Use a preset or enter a custom value.

Temperature change (ΔT)

ΔT is the difference, so °C and K are equivalent in size.

Formula

Q = m · c · ΔT
m in kg, c in J/(kg·°C), ΔT in °C (or K)

All calculations converted to SI internally.
