Understand the calculation

Converted value = original value × source factor / target factor

1 kg·m² = 10000 kg·cm².

Mass moment of inertia has units such as kg·m². The second moment of area in m⁴ is a separate quantity and is not converted here.
Rounding is applied only to displayed results. Very small or very large values may appear in scientific notation.
