In English, currencies should go before the number (i.e. €24.47). Other units should go after (i.e. 3 m2).

But what is the correct order when you mean to give a price per unit (using the slash sign preferably)?

  • €24.47/m2
  • 24.47 €/m2
  • 24.47€/m2

Or is the slash so unusual that you never use it? If this has been asked, thank you for redirecting me. I couldn't find it.

    If you mean 'square metre', the '2' should be a superscript - m². (I had to search the Character Map to find it!) The currency symbol is written before the number but pronounced after it (24 euros). Commented Mar 9, 2023 at 11:24
  • I edited the m² symbol for clarification, thank you for letting me know :D But my concern is about writing the combination of both units: the currency and the surface

  • @Ana In locales where the currency symbol goes after the amount, what is the convention for price per unit? Is it 24.47 €/m²?

The usual order seems to be £x per y or £x/y i.e. (currency symbol) (number) per (unit size) or replace "per" with a slash.

Looking for examples, I find:

on the BBC website £211 per MWh (Business energy prices to be cut by half expected levels, BBC News, 21 September 2022)

on a UK government site £0.10 per kWh (Energy price cap explained, OFGEM, accessed 9 March 2023)

at a British supermarket website £2.10/kg (Silver Spoon Caster Sugar 2Kg, Tesco, accessed 9 March 2023)


Currency symbols are written before the number but pronounced after it (£1 = one pound). The slash can be used to represent per.

So, your first version is the correct one.
