# What is Dimensional Formula of all Fundamental Physical Quantities (Basic Quantities)?

Posted in Dimensional Formulae | Email This Post |All physical quantities can be defined in terms of few fundamental physical quantities like Length, Mass and Time. The unit of these fundamental physical quantities or basic quantities are independent of each other and no one can further resolve it into any other unit. There are 7 basic or fundamental physical quantities. They are **Length, Mass, Time, Temperature, Electric Current, Luminous Intensity and Amount of Substance.

Good

Very good

That’s way more clever than I was expecting. Thanks!

Best

thanks

Thanks solving physics all formula

so bad I am not getting proper information

Please Let us know what information do you want?
