單位換算器是什麼？
The Unit Converter quickly converts between common measurement units across length, weight, temperature, volume, area, speed, time, and digital storage categories. Whether you're cooking with a foreign recipe, traveling internationally, or working on technical projects, quick unit conversion is essential. The world uses two main measurement systems — metric (used by most countries) and imperial (used primarily in the US, UK for some measures, and a few other nations). Converting between them is a frequent need for international communication, trade, and travel. This converter supports hundreds of unit pairs with real-time conversion as you type. It handles everything from common conversions (miles to kilometers, pounds to kilograms) to specialized technical units (pascals to PSI, bytes to gigabytes).

常見問題
▶轉換有多精確？
我們的轉換使用精確的轉換係數，精確到多位小數。溫度轉換使用精確公式（例如：°F = °C × 9/5 + 32）。
▶有哪些單位類別？
我們支援 8 個類別：長度、重量、溫度、速度、面積、體積、資料（數位儲存）和時間。
▶可以在公制和英制之間轉換嗎？
可以！您可以在公制（mm、cm、m、km、g、kg）和英制（英寸、英尺、英里、盎司、磅）單位之間自由轉換。
▶Why are there two measurement systems?
The metric system was developed in France during the 1790s for scientific consistency. The imperial system evolved from older English units. Most countries adopted metric, but the US retained imperial for everyday use, creating an ongoing need for conversion.
▶How accurate are the conversions?
Conversions use precise conversion factors (e.g., 1 inch = exactly 25.4 mm). Results are accurate to multiple decimal places. For scientific or engineering work requiring extreme precision, always verify critical conversions with official standards.
▶What are the most commonly needed conversions?
The most frequently converted units are: miles ↔ kilometers, pounds ↔ kilograms, Fahrenheit ↔ Celsius, gallons ↔ liters, inches ↔ centimeters, and ounces ↔ grams. These cover most everyday international conversion needs.
