For razor you can use  culture  value   String Format new CultureInfo  sv-SE     Model value

Personally i m against using culture specific code  i suggest doing    String Format CultureInfo CurrentCulture    0 C     price    and in your web config do    lt system web gt       lt globalization culture  en-GB  uiCulture  en-US    gt   lt  system web gt    Additional info  https   msdn microsoft com en-us library syy068tk v vs 90  aspx

As others have said  you can achieve this through an IFormatProvider  But bear in mind that currency formatting goes well beyond the currency symbol  For example a correctly-formatted price in the US may be    12 50  but in France this would be written  12 50     the decimal point is different as is the position of the currency symbol   You don t want to lose this culture-appropriate formatting just for the sake of changing the currency symbol  And the good news is that you don t have to  as this code demonstrates   var cultureInfo   Thread CurrentThread CurrentCulture       You can also hardcode the culture  e g  var cultureInfo   new CultureInfo  fr-FR    but then you lose culture-specific formatting such as decimal point    or    or the position of the currency symbol  before or after  var numberFormatInfo    NumberFormatInfo cultureInfo NumberFormat Clone    numberFormatInfo CurrencySymbol             Replace with     or      or whatever you need  var price   12 3m  var formattedPrice   price ToString  C   numberFormatInfo      Output       12 30  if the CurrentCulture is  en-US    12 30      if the CurrentCulture is  fr-FR

I strongly suspect the problem is simply that the current culture of the thread handling the request isn t set appropriately   You can either set it for the whole request  or specify the culture while formatting  Either way  I would suggest not use string Format with a composite format unless you really have more than one thing to format  or a wider message   Instead  I d use    price ToString  C   culture    It just makes it somewhat simpler   EDIT  Given your comment  it sounds like you may well want to use a UK culture regardless of the culture of the user  So again  either set the UK culture as the thread culture for the whole request  or possibly introduce your own helper class with a  constant    public static class Cultures       public static readonly CultureInfo UnitedKingdom            CultureInfo GetCultureInfo  en-GB        Then    price ToString  C   Cultures UnitedKingdom    In my experience  having a  named  set of cultures like this makes the code using it considerably simpler to read  and you don t need to get the string right in multiple places

You need to provide an IFormatProvider    String Format new CultureInfo  en-US      0 C     price

For those using the C  6 0 string interpolation syntax  e g    The price is  price C    the documentation suggests a few ways of applying different a CultureInfo   I ve adapted the examples to use currency   decimal price   12345 67M  FormattableString message     The price is  price C     System Globalization CultureInfo CurrentCulture   System Globalization CultureInfo GetCultureInfo  nl-NL    string messageInCurrentCulture   message ToString     var specificCulture   System Globalization CultureInfo GetCultureInfo  en-IN    string messageInSpecificCulture   message ToString specificCulture    string messageInInvariantCulture   FormattableString Invariant message    Console WriteLine    System Globalization CultureInfo CurrentCulture -10   messageInCurrentCulture     Console WriteLine    specificCulture -10   messageInSpecificCulture     Console WriteLine     Invariant  -10   messageInInvariantCulture        Expected output is     nl-NL      The price is     12 345 67    en-IN      The price is   12 345 67    Invariant  The price is   12 345 67
