What units can I convert with this tool?

The unit converter supports three categories: Length (millimeters, centimeters, meters, kilometers, inches, feet, yards, miles), Weight (milligrams, grams, kilograms, metric tonnes, ounces, pounds), and Volume (milliliters, liters, cubic meters, teaspoons, tablespoons, fluid ounces, cups, pints, quarts, gallons).

How accurate are the conversions?

All conversions use standard conversion factors and are mathematically accurate. Results are displayed with up to 6 decimal places for precision, with trailing zeros removed for cleaner display. For example, 1 inch = 0.0254 meters exactly.

Can I convert between metric and imperial units?

Yes! The converter supports conversions between metric (e.g., meters, kilograms, liters) and imperial (e.g., feet, pounds, gallons) units. For example, you can convert feet to meters, pounds to kilograms, or gallons to liters.

What is the difference between weight and mass?

In everyday use, weight and mass are often used interchangeably. This converter uses weight units for practical conversions (like pounds to kilograms). Technically, mass is measured in kg and weight is a force measured in Newtons, but for unit conversion purposes, the terms are equivalent.

How do I convert cubic meters to liters?

Select the Volume category, enter your value in cubic meters (m³) as the From unit, and select liters (L) as the To unit. 1 cubic meter equals 1000 liters. For example, 2 m³ = 2000 L.

Why does the Swap Units button exist?

The Swap Units button instantly reverses your conversion direction, swapping the From and To units. This is useful when you want to convert in the opposite direction without manually reselecting units. For example, if you are converting meters to feet, clicking Swap will convert feet to meters instead.
