I hate how these terms are used colloquially. Here are wikipedia’s definitions: Conservatism is a cultural, social, and political philosophy and ideology that seeks to promote and preserve traditional institutions, customs, and values. Liberalism is a political and moral philosophy based on the rights of the individual, liberty, consent of the governed, political equality, right to private property, and equality before the law. So no. The definitions are very different. Now you can say that liberals and conservatives are similar in your country or that you live in liberalism and therefore trying to keep it is conservatism, but there is no necessary overlap afaik.

since we’re unironically using wikipedia as a source for some reason, you’re conflating liberalism (en.wikipedia.org/wiki/Liberalism) with social liberalism (en.wikipedia.org/wiki/Social_liberalism). you are the one using the terms colloquially. americans might use the terms conservative and liberal to represent republican voters and democrat voters respectively, but both of those ideologies are different flavors of liberalism as the rest of the world understands it.
