Precision and calculation record

Decimal places in numeric results and text downloads

Rounding changes displayed numbers, not the calculation. Text, fractions, matrices and CSV schedules keep their own formatting. Automatic keeps up to 12 significant digits, with money shown to cents where applicable.

Step-by-step calculation

Inputs are substituted below. Each line evaluates the next operation; intermediate values are displayed to 12 significant digits while the calculation uses full precision.

Saved scenario

Save the current answer, then change an input to compare. This clears when you leave.

Formula and assumptions

Use nonzero temperature change. Assumes no phase change and negligible heat loss; Celsius temperature differences equal kelvin differences.

Automatic precision shows numbers to 12 significant digits. Thousands separators such as 1,000 are accepted; use a dot for decimals.

Using Specific heat calculator

Specific heat = heat transferred ÷ (mass × temperature change).

Use nonzero temperature change. Assumes no phase change and negligible heat loss; Celsius temperature differences equal kelvin differences.

A worked example

With heat transferred (j) = 1000, mass (kg) = 2, temperature change (k) = 5, the specific heat (j/kg·k) is 100.

Before you use the result

Use nonzero temperature change. Assumes no phase change and negligible heat loss; Celsius temperature differences equal kelvin differences.

Example results for heat transferred (j)

These examples use Mass (kg): 2; Temperature change (K): 5. They are reference calculations, not recommended settings.

Heat transferred (J)	Specific heat (J/kg·K)
500	50
1000	100
2000	200
