• "F" for "s4·A²/(m²·kg)".
• "C" for "s·A".
• "S" for "A²·s³/(m²·kg)".
• "H" for "m²·kg/(s²·A²)".
• "V" for "m²·kg/(s³·A)".
• "Ohm" for "m²·kg/(s³·A²)".
• "J" for "m²·kg/s²".
• "N" for "m·kg/s²".
• "Hz" for "1/s".
• "lx" for "cd·sr/m²".
• "lm" for "cd·sr".
• "Wb" for "m²·kg/(s²·A)".
• "T" for "kg/(s²·A)".
• "W" for "m²·kg/s³".
• "Pa" for "kg/(m·s²)".

Overrides:
