The best piece of equipment for measuring a marble would be a caliper, specifically a digital or vernier caliper. This tool allows for precise measurement of the marble's diameter and can also measure its circumference if needed. Alternatively, a ruler could be used, but it would be less accurate for small, rounded objects like marbles.
Feet and inches.
The millimetre.
For a desk like one used in schools the best unit would be pounds. Good luck on your measuring!
Centimeters would be best for measuring a skunk.
The ideal waist size for a 5'9 male who weighs 162 lbs would depend on body composition and muscle mass, but a waist circumference of around 32-34 inches is considered healthy. It's best to focus on overall health and fitness rather than just waist size alone.
It depends on wether you want to shrink your waist permanently, even when you don't wear a corset, or just temporarily to get the minimum waist circumference you can achieve. For permanent shrinking a full corset worn 24/7 will be best. But be aware this will move bones and organs permanently, because your body will adapt to the corset. There are pics on the web, that show ladies who do wear their corsets 24 hrs a day displaying what their waists look like when they take the corset off. All I can say is... incredible! For temporary waist shrinking a waist cincher may be better. If you would like to achieve an extremely tiny waist circumference, the more narrow the cincher is, the tighter you will be able to make it. If you even replace it with a normal waist belt 1 or 2 inches wide, you will be able to reach extreme results. I can pull in my waist to about 19 inches with a belt, while my normal waist circumference is 29 inches...!
A measuring beaker.
A balance is the best tool for measuring mass.

a tape measure
A flexible measuring tape can be used to measure the circumference of a pendulum bob. Wrap the measuring tape snugly around the pendulum bob to determine its circumference. Alternatively, a string can be used to measure the circumference and then measured against a fixed ruler or measuring tape.

A caliper would be the best tool for measuring the width of a pencil lead. It is precise and allows you to measure small dimensions accurately.
a bump would work
