Millimetres
Multiply every linear value by 0.001.
Convert each length before you cube the result.
Choose the unit used on your tape or rule. The worksheet converts length, width and height separately to metres, then multiplies those converted values. It never treats a centimetre as though its factor applies only once to a cubic result.
Five input units, one metre-based calculation.

Centimetres
Multiply every linear value by 0.01.
Metres
Use the entered value unchanged.
Inches
Multiply every linear value by exactly 0.0254.
Feet
Multiply every linear value by exactly 0.3048.
100 cm × 0.01 = 1 m
1 cm³ = (0.01 m)³ = 0.000001 m³
1 m³ ≈ 35.31 ft³
06 / WORKPAD NOTE
Start at the same outer boundary
Align the zero point with one packed edge and read the furthest outer edge. Include fixed packaging and protectors.
07 / WORKPAD NOTE
A metre span is still a linear input
Long pallets and crates use the same three-dimensional formula. The measuring tool changes; the arithmetic does not.
08 / WORKPAD NOTE
Imperial inputs are converted line by line
Inches and feet are accepted for convenience. Their exact linear factors are applied before multiplication, so mixed-unit rows can still share a metre-cubed total.
09 / WORKPAD NOTE
Keep the physical reference with the note
When working in feet, write down which outer points the span covered. A number without its boundary is hard to verify later.
