Base units in science usually means the International System of measurement fundamental units. (SI units - Systeme International) The SI base units are: Base Quantity - - - -Unit - - - - Symbol

length - - - - - - -metre or meter - - m

mass - - - - - - - - - - kilogram - - - kg

time - - - - - - - - - - second - - - - - s

electric current - - - - ampere - - - - A

temperature - - - - - - kelvin - - - - - K

amount of substance - - mole - - - - mol

luminous intensity - - - candela - - - - cd

Note: abbreviations must have a particular case eg K is the symbol for kelvin but k is the symbol for kilo. Three base units? There are three dimensions when an object is located in space? Width, breadth and height but in science all three of these are considered to be a length. Wiki User

meter, liter, gram

There are seven, not three Base Units (not 'basic') in the SI system. These are the metre, kilogram (not gram!), second, ampere, kelvin, candela, and mole. The litre is NOT an SI unit.   Wiki User

Units of measurement that are considered fundamental, such that they cannot be described as a function of other units, are distance, time and mass. It can be seen that other measurements are derived from these fundamental units.   Wiki User

In the SI system, the basic units are

metre : length

kilogram : mass

second : time

ampere : electric current

kelvin : thermodynamic temperature

mole : amount of substance

candela : luminous intensity.   Wiki User
