1. The problem asks: What is the unit for distance? 2. Distance is a measure of how far apart two points are in space. 3. The standard unit for distance in the International System of Units (SI) is the meter, abbreviated as $m$. 4. Other common units for distance include kilometers ($km$), centimeters ($cm$), millimeters ($mm$), miles, feet, and inches, but these are not SI units. 5. The meter is defined based on the speed of light and is the base unit for length in physics and everyday measurements. 6. Therefore, the unit for distance is typically the meter ($m$).
