For example, searching 'Microsoft Apple' in Alpha returns data comparing both companies stock prices, whereas Google top results are news stories mentioning both companies. However, when searching for '10 pounds kilograms,' Alpha rather unhelpfully assumes you want to multiply 10 pounds by 1 kilogram, whereas Google directs you to sites for metric conversions. Change the query to '10 pounds in kilograms' and both give you the result you'd expect (i.e. 4.536 kg)."
