Firefox Address Bar: Your Calculator and Unit Converter

The Firefox address bar is more than just a place to type web addresses. Since version 137, it has included a built-in calculator, and starting with version 141, it also supports unit conversions. These features let you perform quick calculations and conversions without opening extra apps or tabs. This article explains how to use these tools effectively, saving you time and effort.

Using the Calculator Feature

Simple Calculations

To perform basic math, type your equation directly into the Firefox address bar. For example, enter 5 + 3 or 10 * 4. As you type, Firefox instantly displays the result in the drop-down menu below the address bar. This works for addition, subtraction, multiplication, and division, making it ideal for quick arithmetic tasks.

Complex Calculations

The calculator also handles more advanced math. You can combine operations, such as (5 + 3) * 8 or 10^2 / 5. Firefox respects the order of operations, so your results are accurate even for multi-step equations. If you use parentheses, ensure they are balanced to avoid errors.

Converting Units in the Address Bar

Basic Unit Conversions

Starting with Firefox version 141, you can convert units directly in the address bar. Use the syntax: <number><source_unit> to <destination_unit>. For example, type “45 km to mile” to convert 45 kilometers to miles. The result appears instantly in the dropdown menu. Supported conversions include length (e.g., meters to feet), temperature (e.g., Celsius to Fahrenheit), and more.

Time Zone Comparisons

The address bar also supports time zone conversions. For example, type 5 PM PDT to EST to see what time 5 PM Pacific Daylight Time is in Eastern Standard Time. You can also use now to PDT to compare your current time to another time zone. This is handy for scheduling across regions.

Conversion Syntax

The general format for unit conversions is <number><source_unit> [in|to|=] <destination_unit>. For example, 100 cm to inches, 100 cm in inches, or 100 cm = inches all work. Be precise with unit abbreviations (e.g., km for kilometers, ft for feet) to ensure accurate results.
