AI Unit Converter (Natural Language)

The AI Unit Converter lets you convert units by simply typing a question. Write 5 miles in km, 70 mph to km/h or 2 cups of flour in grams, and the exact answer appears as you type, together with the formula, the same amount in related units and a comparison that makes the number easy to picture.

Why it's different

• Exact. Every result is calculated by code from exact unit definitions, never guessed by an AI.
• Instant and free. Normal questions are answered in your browser as you type, without using a credit.
• Understands harder questions. For something like half a stick of butter plus 3 tbsp in grams, the AI reads the question and code does the math.
• Cooking-aware. Cups to grams uses the weight of the actual ingredient: flour, sugar, butter, rice and more.
• Makes numbers meaningful. See a marathon as about 461 American football fields.

What it converts

Length, weight, volume (US and UK), area, temperature, speed, time, data (KB/MB/GB and KiB/MiB/GiB), energy and calories, pressure, power, angles and fuel economy (mpg and L/100 km).

Tips

• Say the ingredient for cooking conversions: 1 cup of sugar in grams.
• Use uk pint or imperial gallon for British measures.
• Leave out the target unit to see the amount in the most common related units.

Frequently asked questions

How do I use the natural-language unit converter?

Type your conversion the way you'd say it: 5 miles in km, 350 F to C, how many tablespoons in a cup, 2 cups of flour in grams. The answer appears instantly as you type, with the formula, the same amount in related units and a real-world comparison.

Is the answer calculated by AI?

No. Every number is calculated by code from exact unit definitions, such as 1 mile = 1,609.344 meters. For questions the converter can't read on its own, the AI only works out which units you mean; the math is still done by code.

How many grams are in a cup?

It depends on the ingredient: a US cup of water weighs about 237 g, but a cup of all-purpose flour only about 125 g and a cup of sugar about 200 g. Type something like 2 cups of flour in grams and the converter uses the right weight for that ingredient.

How do I convert Fahrenheit to Celsius?

Subtract 32 and multiply by 5/9: 350 °F is (350 − 32) × 5/9 ≈ 176.7 °C. Type 350 F to C to see it with the formula and nearby values.

What's the difference between a US and a UK gallon or pint?

A US gallon is 3.785 liters and a UK (imperial) gallon 4.546 liters; a US pint is 473 ml and a UK pint 568 ml. Type uk pint or imperial gallon to use the British units.

Is it free?

Yes. Conversions the page can read on its own are instant and never use a run. Only questions that need the AI to read them use one of your free daily runs.
