Depending on the shape:
Standard rectangular bath - length x breadth x height
Probably gallons or liters
Depends on the internal shape. If it was perfectly square, you could go with internal depth by width times length. But most bathtubs are curved and you'd be hard pressed to get the exact volume with a measuring tape.
The best bet is to fill it with water, measuring the water as it is added, until you've filled it and have a count of the number of gallons it took to fill it. Each gallon is equal to 231 cubic inches, and 1728 cubic inches is a cubic foot. If you measure by liters, each liter is one cubic decimeter and it takes 1,000 liters to make a cubic meter.
You could get a small measuring jug, turn the tap on and measure the rate at which the water is coming out by timing how long it takes to fill the jug. Then time how long it takes to fill the entire bath, use the rate you just found to calculate the volume. For accuracy, measure the rate several times and take an average.
The common metric unit of volume is the liter, which would be appropriate to measure this amount of water. The SI unit of volume is the cubic meter, though.
The simplest metod is to use a calibrated bucket.
Frequently the volume is 15-20 L for a bucket.

liter
For most of the world, it's probably in Liter, a standard unit to measure capacity or space or volume. In the US, gallon is the stand for fluid capacity, but cubic feet is often used for space capacity.
The capacity of a bathtub is around 80 litres.

The capacity of a bathtub could be appropriately measured in liters.
Only if the bathtub has a capacity of 45 gallons.
