A Microscope.
Small things such as insects or a fine mesh, to larger things where precision is important - such as kitchen units and appliances.
It depends. Very small amounts of things are measured in grams, a bit larger is ounces, larger is pounds, and the largest is tons, which is 2,000 pounds.
A general answer to your question would be: tools. For example, a microscope is a tool that makes it easier to understand things that are too small to observe directly. An x-ray machine is a tool that allows us to see inside of things that are too hard to see inside of directly. A knife is a tool that allows us to cut up large things to see what is inside of them.
a gram is larger since micro means small
The instrument used to make extremely small things look larger so humans can see them is a microscope.
A Microscope.
For example, a bicycle pump will do that.
