Either a ruler or a caliper.
A cup of yogurt or a bottle of hot sauce are some things that hold 100 millimeters.
It means to figure out the length and width of a specific item. It can be millimeters, centimeters, inches, feet, yards... Etc... A ruler is used for measuring objects and if the object is circular, you can use a string and mark the measurement on the string to measure it on the ruler.

There is no equivalence. A millimetre is a measure of length or distance in 1-dimensional space while a gallon is a measure of volume in 3-dimensional space. The two measure different things and, according to basic principles of dimensional analysis, conversion from one to the other is not valid without some addition information.
You cannot calculate standard deviation for objects such as concrete cubes - you can only calculate standard deviation for some measure - such as side length, surface area, volume, mass, alkalinity or some other measure.
Millimeters, inches, light-years, miles, it's all the same: Measure all four sides and add their lengths together. That's what "perimeter" means. For some figures there really is a formula. For example, since a square or a rhombus has all four sides the same length, you can just measure one of them and multiply by 4. But the sides of a trapezoid (not "TARPezoid") don't have any particular relationship in terms of length.
There are no millimeters in a milligram. There can't be. Millimeters are units of LENGTH: a millimeter is one-thousandth of a meter (a meter measures a bit more than 39 inches). Milligrams, on the other hand, are units of MASS (more usually, they are called units of WEIGHT). One thousand milligrams equal one gram. About 454 grams equal one pound weight. Obviously, since milligrams and millimeters measure different things (weight and length respectively), they can't be expressed in terms of each other. You might as well ask "how many cupfuls in a mile", or "how many inches in a ton". Millimeters and milligrams are units in the SI system of measurement, which developed from the metric system. The SI system is used in most countries of the world. In some countries (the USA is one) units from much older systems are used: inches, pounds, gallons, etc.
A convex lens has a focal length of 150 millimeters. Some politicians will go to any length to keep their positions. The horse won the race by barely a length.
you can use a balance table for some small objects.
