Unit Converter

Choose Length, Weight, or Temperature, enter a number, pick the two units, and click Convert. The result shows at most six decimal places. Currency is not one of the categories.

How to use

  1. In the first menu, choose Length, Weight, or Temperature. The unit menus refill when you change that category.
  2. Type the number. The field starts at 1. Set the unit you have and the unit you want. Length lists Meters, Kilometers, Centimeters, Millimeters, Miles, Feet, and Inches. Weight lists Kilograms, Grams, Pounds, and Ounces. Temperature lists Celsius, Fahrenheit, and Kelvin.
  3. Click Convert. The result line does not move until that click. Changing a menu alone leaves the previous result on screen.

When it helps

Length covers m, km, cm, mm, mi, ft, and in. Weight covers kg, g, lb, and oz. Temperature converts among Celsius, Fahrenheit, and Kelvin with the standard offsets, not a custom scale. The figure uses at most six decimal places, so a long fraction is shortened and a whole number does not grow trailing zeros.

Money is not converted here. A percent of a price belongs on the Percentage Calculator, which has two separate Calculate buttons. A running pace from distance and time belongs on the Pace Calculator, which asks for distance, km or miles, and hours, minutes, and seconds.

Limits

There is no currency category, and no list for area, volume, or file size. Do not type a dollar amount and expect an exchange rate. Six decimal places is a cap on the display, not a promise that six digits always appear.

You must click Convert. Typing a new number does not refresh the result by itself. Kelvin is on the temperature menu together with Celsius and Fahrenheit. No other temperature unit is hidden in that list.

Questions

Which length and weight units are on the menus?

Length is m, km, cm, mm, mi, ft, and in, labeled from Meters through Inches. Weight is kg, g, lb, and oz. Those menus are the full set for those categories.

Does every result show six decimals?

No. Six is the maximum. Trailing zeros are not padded on. Click Convert again after you change the number or either unit.

Can I convert dollars or euros here?

No. The categories stop at Length, Weight, and Temperature. A percent of an amount is a different calculator, and pace is another.
