About Light Minutes
A light minute (lm) is the distance light travels in one minute through a vacuum, equal to 17,987,547,480 meters or about 17.99 million kilometers. The Sun is approximately 8.3 light minutes from Earth, meaning sunlight takes 8 minutes and 20 seconds to reach us. Venus ranges from 2 to 14 light minutes from Earth depending on orbital positions. This unit provides a convenient scale for discussing distances within the inner solar system and helps visualize the time delays in space communications.
About Thou
A thou (also called mil) is one thousandth of an inch, equal to 0.0254 millimeters or 25.4 micrometers. This unit is commonly used in engineering and manufacturing in countries that use imperial measurements, particularly for specifying tolerances, wire gauges, and thin material thicknesses. For example, a standard plastic bag might be 1-2 thou thick, a sheet of paper is about 4 thou, and precision machined parts often have tolerances measured in thou. Electronic circuit board copper traces are typically 1.4 thou thick.
