I get where you're coming from.
This would mean that to and in would have very different meanings in conversions.
How would you handle this with currencies for example. If someone searches for USD in EUR, should this return the result for 1 USD converted to EUR or how many USD fit in 1 EUR (= 1 EUR converted to USD)?
Should the presence / absence of a leading number switch the meaning of the in?
