+# Criteria for adding quantities and units
+
+Related wiki page: https://github.com/angularsen/UnitsNet/wiki/Adding-a-New-Unit#a-quantity-is-a-good-fit-to-add-if-it
+
+To avoid bloating the library, we want to ensure quantities and units are widely used and well defined.
+Avoid little used units that are obscure or too domain specific.
+Ask for justification and use cases if this is not clear.
+
+### A quantity is a good fit to add, if it
+
+- [x] Is well documented and unambiguous, e.g. has a wiki page and generally easy to find on Google
+- [x] Is widely used, preferably across domains
+- [x] Has multiple units to convert between (e.g. `Length` has kilometer, feet, nanometer etc.)
+- [x] Can convert to other quantities (e.g. `Length x Length = Area`)
+- [x] Can be represented by a `double` numeric value, integer values are not well supported and may suffer from precision errors
+- [x] Is not [dimensionless/unitless](https://en.wikipedia.org/wiki/Dimensionless_quantity) (consider using `Ratio`)
+
+### A unit is a good fit to add to a quantity, if it
+
+- [x] Is well documented and unambiguous, e.g. has a wiki page or found in online unit converters
+- [x] Is widely used
+- [x] Can be converted to other units of the same quantity
+- [x] The conversion function is well established without ambiguous competing standards
+
+### Avoid X-per-Y units
+
+There are many variations of unit A over unit B, such as `LengthPerAngle` and we want to avoid adding these unless they are very common.
