A collection of major unit conversion factors and formulas for distance, weight, volume, and temperature.
Overview
Unit Conversions
Unit conversion is an essential tool for performing numerical transformations between different measurement units. Based on international standards such as NIST (National Institute of Standards and Technology) Handbook 44, this data systematically organizes conversion factors and formulas between commonly used units in daily life and scientific/industrial fields, including distance (kilometers and miles), weight (kilograms and pounds), volume (liters and gallons), and temperature (Celsius and Fahrenheit). These conversion factors are fundamental knowledge essential for international trade, scientific research, engineering, and everyday life.
