As of my last update, the exchange rate for Saudi Riyal (SAR) to US Dollar (USD) is approximately 1 SAR = 0.27 USD.
Using that rate:
- 100 SAR would be approximately 27 USD
- 200 SAR would be approximately 54 USD
Please note that exchange rates can fluctuate, so it's a good idea to check a reliable financial news source or a currency converter for the most current rates.
