The micrometer is all about precision and is common in engineering where exact measurements are critical.

Precision Tool

A micrometer is not for rough measurements; it's for when you need to be highly accurate, to one thousandth of a millimeter.

Measurement Context

Don't confuse a micrometer with common measuring tools like rulers; it's for much smaller dimensions.

Not a Ruler

Think of a micrometer as incredibly small; it's used to measure things you can't see with just your eyes.

Microscopic Scale

Micrometers are key in science, especially biology, to measure cells and tiny organisms.

Science and Biology

Remember that a micrometer is much smaller than a millimeter; there are one thousand micrometers in a millimeter.

Not Millimeters

 picture just like this and if they can see from the scale bar it's just one micrometer in length so it's really tiny but despite being so tiny bacteria and other microbes can do really amazing things they usually have a bad rep right because they contaminate our food and they make us sick but there are other

 A cube measuring one micrometer on each side, that's one millionth of a meter, would have a total surface area of six square micrometers. And its volume would be one cubic micrometer. This would give us six units of surface area for every single unit of volume, a six to one ratio.

 Hello. Don't leave me hanging. That's it. We've equaled the world record. I now want to break the world record. Okay, so, here we have the world record beater, potentially. Okay. I'm gonna make this official by using this little, um What's this called, a micrometer?

 and we recorded it at thousands of frames per second, but even if you look very closely, all you'll see are some leaves that are pretty much just sitting there doing nothing, because our sound only moved those leaves by about a micrometer.

 I call it the visual microphone. We actually extract audio signals from video signals. And just to give you a sense of the scale of the motions here, a pretty loud sound will cause that bag of chips to move less than a micrometer.

 with only a 25 micrometer width. Long, fine fibers can wrap around one another better than shorter, less fine fibers, which means those long, fine fibers make stronger threads that hang together better as fabric.
