500万 can be translated to "five million" in English. This comes from the fact that "万" in Chinese (pronounced "wan") means "ten thousand," and "500" in Chinese is the same as "five hundred" in English. So when you combine these two numbers, you get "five hundred ten thousands," which is equivalent to "five million" in English.

Here are some example sentences in English and Chinese to illustrate how you might use this number in a sentence:

English: "She won five million dollars in the lottery."

Chinese: "她在彩票中赢得了500万美元。"

English: "The company reported a profit of five million dollars this quarter."

Chinese: "这家公司本季度报告了500万美元的利润。"

English: "The population of the city is five million people."

Chinese: "这个城市的人口是500万。"
