How Metriqcon works

Every unit in a category is stored against one base unit — meters for length, kilograms for weight, liters for volume. To convert, Metriqcon multiplies your value into the base unit and then divides by the target unit's factor, so any unit converts to any other in a single exact step. Factors use official definitions: 1 inch is exactly 2.54 cm, 1 pound is exactly 0.45359237 kg, and 1 US gallon is exactly 3.785411784 liters.

Temperature is the exception, because the scales don't share a zero point. Here we use offset formulas: °F = °C × 9/5 + 32, K = °C + 273.15, and °R = °F + 459.67.

The value box is a real math parser, not a number field. Type (12\*4)+6.5, 25\*2.54 or 3^2 and it evaluates the expression before converting, following standard order of operations. Everything runs in your browser, so results appear instantly and nothing you type leaves your device.

Frequently asked questions

Which unit categories does Metriqcon support?

Eight categories: length, weight & mass, temperature, area, volume, speed, time, and data storage — 68 units in total, from millimeters to terabytes. Every unit in a category converts to every other unit instantly.

Can I type math expressions instead of a plain number?

Yes. Type expressions like (12\4)+6.5, 25\*2.54, or 100/3 directly into the value box. Operators + − \ / ( ) ^ % are supported, and × ÷ − are accepted too. The result updates as you type.

How precise are the results?

Results are shown with up to 10 significant digits, and conversion factors use exact definitions where they exist (for example, 1 inch = 2.54 cm exactly). Rounding only appears in the reference tables for readability.

How many centimeters are in an inch?

1 inch = 2.54 centimeters, exactly. To go the other way, divide by 2.54 — or use the cm to inches page for a live converter and reference table.

How do I convert Celsius to Fahrenheit?

Multiply the Celsius value by 9/5 and add 32: °F = (°C × 9/5) + 32. So 20 °C = 68 °F. The reverse is °C = (°F − 32) × 5/9. You can type the math directly into the converter.

How many feet are in a meter — and miles in a kilometer?

1 meter = 3.28084 feet, and 1 kilometer = 0.621371 miles. For weight, 1 kilogram = 2.20462 pounds. Each popular pair has its own page with the exact factor and a conversion table.

Is Metriqcon free to use?

Yes — completely free, with no sign-up, no app install, and no limits. It works in any browser on phone, tablet, and desktop.
