I’m preparing for my project presentation and I have to mention the second moment of area which has the units of length to the fourth power i.e. mm^4.

How would you say mm^4:

[LIST=1]

  • Millimeters to the power of four
  • Millimeters to the four
  • Quartic millimeters
  • Biquadrate millimeters
  • Tesseractic millimeters
  • mm caret four :p
  • Other [/LIST]

    Currently I’m liking option 3.

    What are your suggestions?

    • 2

    spissitudal mm?

    3

    IMO 1, 2, or 3

    4

    You said it, right there. Millimeters to the fourth power. Crystal clear in meaning.
