Unit Converter

When to use?

Use it to check inch-based clothing sizes in cm on overseas shops, to convert cups and ounces in a foreign recipe to mL, or to understand a weather app's Fahrenheit temperature in Celsius.

How to use

• Choose the category to convert (length, weight, temperature, area, volume).
• Enter the value and the source unit.
• Select the target unit to see the converted result.

Input Explanation

Enter a number and choose the source and target units. Temperature supports conversion between Celsius (°C), Fahrenheit (°F), and Kelvin (K).

Calculation Basis

Each unit uses a defined conversion factor (e.g. 1 inch = 2.54 cm), multiplying or dividing the input to reach the target unit.

Usage Examples

• Check overseas clothing sizes - Convert US clothing sizes (inches) to centimeters.
• Convert recipe units - Convert cups and fluid ounces to mL and L.
• Understand weather temperatures - Convert Fahrenheit (°F) to Celsius (°C).

Examples

• 1 inch → 2.54 cm, 1 pound → 453.6 g
• 100°F → 37.8°C (body-temperature range)

Cautions

• Results depend on input conditions, so do not use them as the sole basis for financial or legal decisions.
• This is for everyday conversion rather than engineering-grade precision; for ultra-fine control, check the relevant standard.

Guides

Conversion basis

For each quantity (length, weight, temperature, volume), a conversion factor links SI and non-SI units. For example, 1 inch = 2.54 cm and 1 pound = 0.4536 kg.

Temperature conversion

To convert Celsius (°C) to Fahrenheit (°F), use °C × 9 ÷ 5 + 32. To go the other way, use (°F − 32) × 5 ÷ 9.
