Below is an instruction that describes a task. Write a response that appropriately completes the request in English. Please answer in English.

### Instruction:
A shopkeeper bought 150 packets of milk. Each packet contained 250 ml of milk. If one fluid ounce is equal to 30 ml, how many ounces of milk did he buy?

### Response:
The total amount of milk that the shopkeeper bought is 150 * 250 = <<150*250=37500>>37500 ml.
Since one ounce equal 30 ml, the total amount of milk that the shopkeeper bought in oz is 37500/30 = 1250 oz.
#### 1250
