The Hidden Superpower of Convert: Natural Language Input

Natural language input in Convert app
TL;DR
  • Type conversions naturally — "50 usd to eur" or "how many cups in 500ml"
  • Convert understands abbreviations, full names, and common phrases
  • Results appear instantly as you type, no submit button needed

Most people open Convert, see the big text field, and immediately look for dropdown menus. I don't blame them. That's how every other converter works.

But here's the thing — those menus are optional. You can just type what you're thinking and Convert figures out the rest.

Just Type What You Mean

When I'm cooking and need to know how many tablespoons are in half a cup, I don't think "volume, cups, tablespoons, 0.5." I think "half a cup in tablespoons."

So that's exactly what you can type into Convert. Or "0.5 cups to tbsp." Or "half cup = ? tablespoons." All of these work.

The result shows up instantly. No tapping a convert button. No waiting. You see the answer before you've finished typing.

Examples That Work

I've had people email me surprised that certain queries actually work. So here's a quick list of things you can type:

Currency conversions:

  • 50 usd to eur
  • 100 dollars in pounds
  • 500 yen to aud
  • how much is 75 euros in usd

Distance:

  • 5k in miles
  • marathon in km (yes, it knows a marathon is 26.2 miles)
  • 100 yards to meters
  • 3 feet in cm

Temperature:

  • 72f in celsius
  • 20 degrees c to f
  • body temp in fahrenheit

Cooking:

  • 2 cups in ml
  • 3 tablespoons to teaspoons
  • 500g flour in cups
  • 1 stick butter in grams

Weight:

  • 150 lbs to kg
  • 70 kilos in stone
  • 5 oz in grams

Abbreviations and Full Names

Convert understands both. Type "kilometers" or "km." Type "pounds" or "lbs" or "lb." Type "celsius" or just "c." Whatever feels natural.

For currencies, you can use the three-letter codes (USD, EUR, GBP) or just say "dollars," "euros," "pounds." Convert knows what you mean. Although if you type "dollars" without specifying, it assumes US dollars — if you want Canadian or Australian, throw in "cad" or "aud."

The Shortcut Nobody Notices

Here's my favorite trick: you don't need to type "to" or "in."

Just type 100 km miles. Convert sees a number, a unit, and another unit. It figures out you want to convert between them.

This is huge when you're doing quick conversions one-handed. Fewer characters means faster answers.

When Menus Still Make Sense

I'm not saying the category browser is useless. Sometimes you don't know what unit you're looking for. Or you want to browse all the fuel economy options to see what's available.

But for everyday conversions — the stuff you do ten times a week — natural language is faster. Way faster.

Try it yourself. Open Convert, ignore the menus, and just start typing. I think you'll be surprised how much it understands.
