You use a suction bulb to gather a specific amount of the liquid when using a pipette, and you can push the bulb down to let the liquid out. So, you can control the amount of liquid in a pipette.
But with the burette, you open the tap to let the liquid out and close it if you want to stop. But you cannot control the amount of liquid in it.
Hence a pipette is more accurate. Both are commonly used in titration, which is a method used in chemistry to determine the molarity of an acid or a base.

You know in SI Units, metres (m) is used for measuring length, kilograms (kg) is used for measuring weight, etc. So why use metres and kilograms? Why not use for example, his TV screen is as long as 3 shoes, instead of using something like 0.5m long?

Well in my opinion,
It is quite inaccurate to use items such as shoes to measure length, because shoes come in a variety of different sizes. Sure, they can standardize a shoe size, but that would mean everyone must wear the same shoe length or something, which is pretty impossible. So we use a unit which is known worldwide, such as metres! Everyone knows one metre is one hundred centimetres. They know the exact length of one metre. Which is much more accurate than saying 5 shoes long, because other people might not know how long is your idea of a shoe.

O
h and another reason why SI Units are used because it is globally recognised, so for example a scientist does the experiment and writes down the procedures and stuff, other people in other countries in the world can understand whatever that scientist is writing.

this is what i think...><
