How much is 20 vara?

Could you please clarify for me, how much is exactly 20 vara in terms of a more widely recognized currency, such as US dollars or euros? I understand that vara may be a specific unit of measurement or currency in a particular region or context, but I'm not familiar with it. Is there a conversion rate or a standard value that I can use to determine its worth? Additionally, is this currency widely accepted, or is it more niche and specialized? Thank you for your help in clarifying this for me.
