The calculator app on IOS uses yahoo.finance for currency conversions. I noticed some niche currencies like GTQ,FKP,BZD and many more. However, there is no Kenyan Shillings to be found. Considering how Kenyans tourism is boosting as a result of their safari and donation aids. Adding KES into your website to be incorporated into the calculator would be incredibly efficient.
I am personally travelling in January and would LOVE to see this updated through.

Thank you.
