Measuring Tools

1 micrometer = 0.001 millimeter

An extremely accurate device used as an instrument for measuring the distance between two points. Often used in machining.

if its on a car or truck (brake caliper) it is how the emergency brake works, usually on the rear, it has a cable that turns the cylinder inside the caliper

There is no other name that I've ever heard. A spirit level is just that.

If you are dealing with something microscopic, you dont want to say that it is say 0.000005 metres in size, it looks messy. Instead you can say 5 microns (micrometres)

This is good for the likes of cell sizes

Some tools that are used in science include microscopes, tweezers, telescopes, computers, maps, and Petri dishes. Other tools include magnifying glasses, chemicals, and even Bunsen burners.

Blades have stud marks every 16􀀀 on English lines, and truss center marks every 19.2 inches on 1􀀀 wide English lines this information is a copy and paste from this web site http://catalog.starrett.com/catalog/images/objects/4200/4108.pdf

a plastic ruler or some string that can be measured once off the pizza

If its a simple shape you can take measurements with a ruler, calipers or tape measure and calculate it.

For simple as well as more complex shapes, if you know the material it is made from, you can work out the volume by taking the mass of the object and dividing by the density of the material, since; density = mass/volume

If you don't know the density, then you can work out the volume by submerging the object in water, and measuring the volume of water that is displaced.

Yes you can by standing on top of the cliff and stand on the end of the tape measure and throw the heavy end down.

The Hand Axe, out of which developed- the Knife. the knife is the first weapon as such mentioned in the Bible.

The least count of the micrometer screw can be calculated using the formula given below:

Least count

= 0.01 mm

Depending on the size of it id say either a 15cm ruler or a 30cm ruler.

.0001 meters

The abbreviation for micrometer is mic. (Pronounced as Mike)

A number and a unit

A micrometer is one millionth of a meter, a millimeter is one thousandth of a meter. So there are one thousand micrometers in a millimeter.

cgs (centimetre,gram,seconds) or SI system i.e mks (metre, kilogram,seconds)

A digital scale is a scale that measures mass but the numbers pop up digitally.

4 centimeters=40,000 micrometers

The abbreviation for micrometer is µm

measuring cup

It is a millionth of a metre.
