Symbols

There is no universally agreed symbol but the following are used:

• cubic mile
• cu mile
• cu mi
• cu m (this can be confused with cubic metre, however, mi is standard and m is rarely used)
• mile/-3
• mi/-3
• m/-3 (this can be confused with cubic metre, however, mi is standard and m is rarely used)
• mile^3
• mi^3
• m^3 (this can be confused with cubic metre, however, mi is standard and m is rarely used)
• mile³
• mi³
• m³ (this can be confused with cubic metre, however, mi is standard and m is rarely used ^{["m is rarely used": blatant nonsense for m with and without exponent 3]}
