Using trigonometry, astronomers now know that the distance from the Earth to the sun is approximately 92,955,820.5 miles (149,597,892 kilometers). This incredible degree of accuracy is possible because the speed of light is known very precisely and extremely accurate clocks are used to time the radar reflection. Radar can’t be used to determine the distance to the Sun directly because the Sun doesn’t have a solid surface to reflect the radar efficiently.

93,000,000 Miles from the Earth to the Sun. That would be 1 AU which means 1 astronomical unit.

well, if light travels at 3x10^8 m/s, and the light from the sun takes 8 minutes to reach earth, that mean that the sun is approximately 1.44x10^11 meters away. now YOU convert that to miles. hahaha.
