In the metric system, the meter is used, often combined with suitable prefixes, such as millimeter, kilometer, nanometer, etc.Other commonly used units are:Imperial units: inch, foot, mileAstronomy: AU, light-year, parsec
I think those are miles, feet, inches, yards (measuring distance) and pounds, ounces, gallons (measuring weight). For temperature it is Fahrenheit (used only by Americans and Belize)
Please note that the metric system is the world-wide standard. If by "standard" you mean the Imperial system (the system commonly used in the USA), the similarities are that the systems are designed to measure, and that they both have units to measure the same type of thing, for example length/distance, area, volume, temperature, etc.
