Siri Does Math! Four Ways to Put Her to Work


If you’ve had your iPhone or iPad for any length of time, you’ve undoubtedly had some experience with Siri, Apple’s built-in personal assistant that can be summoned by pressing and holding the Home key on the front of your iDevice. Siri can perform hundreds of tasks and answer thousands upon thousands of questions, including math problems. Whether you’re checking a homework assignment or trying to figure out how much of a tip to leave your restaurant server, here are four ways you can put Siri’s math wizardry to work for you.

Convert measurements

Cookbooks used to have a chart in the appendix that could help you to figure out simple conversions, like how many ounces are in a cup. With more and more of us getting our recipes from the internet instead of Betty Crocker, though, these helpful charts are harder to find.

Thankfully, Siri can easily convert measurements for you. Press and hold the Home key to call up Siri, then ask your question in natural language.

Figure out a tip

Love it or hate, tipping is a part of life in the service industry. If you eat out, hail a cab or take the family on a cruise, you’ll need to figure out just how much money to leave behind as a courtesy tip.

Make quick and easy work of this task with Siri.
