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

Mass = volume × density. Subtract holes and hollow cores before entering volume. No alloy-density table or nominal section database is guessed; use the actual specification.

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

A worked example

Example inputs: net metal volume (m³) = 0.01, material density (kg/m³) = 8000. Solid metal mass (kg) = 80.

Before you use the result

Mass = volume × density. Subtract holes and hollow cores before entering volume. No alloy-density table or nominal section database is guessed; use the actual specification.

Example results for net metal volume (m³)

These examples use Material density (kg/m³): 8000. They are reference calculations, not recommended settings.

Net metal volume (m³)	Solid metal mass (kg)
0.005	40
0.01	80
0.02	160
