How much should I pay as Sadaqah Fitr?

I know the following hadith: >The Prophet (ﷺ) ordered (Muslims) to give one Sa' of dates or one Sa' of barley as Zakat-ul-Fitr. The people rewarded two Mudds of wheat as equal to that. > > https://sunnah.com/bukhari/24/108 I want to ask the precise amount in cash that this is equal to in USD for the current year. Please mention the rates as in Saudi Arabia and Iran.
