The other value will be returned. The formula is as follows: To convert pounds per square inch to kilopascals(PSI to KPA), multiply the PSI value by 6.894757293168361. To convert kilopascals to pounds per square inch(KPA to PSI), multiply the kpa value by .14503773773020923.
Engineering drawing shares some traits with artistic drawing in that both create pictures. But whereas the purpose of artistic drawing is to convey emotion or artistic sensitivity in some way (subjective impressions), the purpose of engineering drawing is to convey information (objective facts).
This includes practically all inventions except compositions of matter or processes, but a drawing may also be useful in the case of many processes. The drawing must show every feature of the invention specified in the claims, and is required by the U.S. patent office rules to be in a particular form.
