As we know One erg/mm² is equal to 100 µN/mm (1 erg/mm² = 100 µN/mm).

To convert Erg/Square Millimeter to Micronewton/Millimeter, multiply your erg/mm² figure by 100.

Example : convert 25 erg/mm² to µN/mm:

25 erg/mm² = 25 × 100 µN/mm = µN/mm

To convert Micronewton/Millimeter to Erg/Square Millimeter, divide your µN/mm figure by 100.

Example : convert 25 µN/mm to erg/mm²:

25 µN/mm = 25 ÷ 100 erg/mm² = erg/mm²
