Astronomical Unit
An astronomical unit (AU) is a standard space measurement based on the distance from the Earth to the Sun—about 149.6 million kilometers or 93 million miles. It helps describe solar system distances in practical numbers rather than extremely large values.
Astronomers use AU values to measure orbits of planets, asteroids, and comets relative to Earth.
Yard
A yard (yd) is an imperial unit of length equal to 3 feet or 0.9144 meters. It is commonly used in the United States and the United Kingdom for measuring fabric, sports fields, garden dimensions, and other medium-sized distances. Because it connects feet and miles, the yard plays a key role in everyday imperial measurements.
Whether comparing lengths for home projects, shopping, or athletics, converting yards into inches, feet, or meters is often useful. A conversion tool makes switching between systems quick and accurate.
