What about micrometers?

#1, I love the name, #2, A micrometer is 1000 times smaller than a centimeter.

Is there anything before 'Millimeter' and after 'Kilometer' ?

technically, as with any SI unit, yes there is. practically: smaller than milli meter: yes. larger than kilo meter: no this table shows all the possible prefixes: https://en.wikipedia.org/wiki/Metric_prefix in physics, you occasionally come across nano meters, one nanometer = 10^-9 meters or 0.000000001 meters going bigger, you could technically have a mega meter which would be 1000 kilometers, but i have never seen this in practice and most people would misunderstand you (in a metric country)

Okay so if y'all don't get this, let me give you an example. So, 1 kilogram = 1,000 grams, right? So, if the question asks you how many grams are 4 kilograms, you multiply 4 by 1,000 which is 4,000. Because if 1 kilogram = 1,000 grams, 4 must be 4,000 grams.

thanks btw also if i understood ur so kind

Is there more measurements than just this?

Yes- nanometers and micrometers are some smaller measurements

What is the difference between km and M?

a km is a kilometer, and an M is a meter. There are 1,000 meters in a kilometer. In other words, one meter is 1/1,000 of a kilometer or 0.001 of a kilometer.

Does anyone know how long 1 meter = ----- kilometer and how long 1 kilometer = -----meter

The prefix 'kilo' means 1000, so there are 1000 meters for every kilometer and there are 0.001 kilometers for every meter.

I get messed up with km to mm.

Converting from km to m requires multiplying by 1,000, because there are 1,000 m in one km. Converting m to mm requires multiplying by 1,000, because there are 1,000 mm in one m. It follows from these two facts that converting from km to mm requires multiplying by 1,000*1,000=1,000,000. Have a blessed, wonderful day!

What is distance?

Distance measures length. For example, the distance of a road is how long the road is.

In the metric system of measurement, the most common units of distance are millimeters, centimeters, meters, and kilometers.

How big are metric units of distance?

A paper clip is about 1 millimeter thick.

A fingernail is about 1 centimeter wide.

The length of a guitar is about 1 meter.

A kilometer is equal to 1000 meters. It is a little over half of a mile.

Converting larger units to smaller units

1, start text, space, c, e, n, t, i, m, e, t, e, r, end text, equals, start color #1fab54, 10, end color #1fab54, start text, space, m, i, l, l, i, m, e, t, e, r, s, end text
1, start text, space, m, e, t, e, r, end text, equals, start color #1fab54, 100, end color #1fab54, start text, space, c, e, n, t, i, m, e, t, e, r, s, end text
1, start text, space, m, e, t, e, r, end text, equals, start color #1fab54, 1, comma, 000, end color #1fab54, start text, space, m, i, l, l, i, m, e, t, e, r, s, end text
1, start text, space, k, i, l, o, m, e, t, e, r, end text, equals, start color #1fab54, 1, comma, 000, end color #1fab54, start text, space, m, e, t, e, r, s, end text

To convert larger units to smaller units we multiply the number of larger units by the green conversion factor for the appropriate smaller units.

Example: Converting meters to centimeters:

1, start text, space, m, e, t, e, r, end text, equals, start color #1fab54, 100, end color #1fab54, start text, space, c, e, n, t, i, m, e, t, e, r, s, end text
start color #11accd, 11, end color #11accd, start text, space, m, e, t, e, r, s, end text, equals, start color #11accd, 11, end color #11accd, times, start color #1fab54, 100, end color #1fab54, equals, start color #11accd, 11, end color #11accd, start color #1fab54, 00, end color #1fab54, start text, space, c, e, n, t, i, m, e, t, e, r, s, end text

Converting smaller units to larger units

1, start text, space, m, i, l, l, i, m, e, t, e, r, end text, equals, start fraction, 1, divided by, start color #7854ab, 10, end color #7854ab, end fraction, start text, space, c, e, n, t, i, m, e, t, e, r, end text

1, start text, space, c, e, n, t, i, m, e, t, e, r, end text, equals, start fraction, 1, divided by, start color #7854ab, 100, end color #7854ab, end fraction, start text, space, m, e, t, e, r, end text

1, start text, space, m, e, t, e, r, end text, equals, start fraction, 1, divided by, start color #7854ab, 1, comma, 000, end color #7854ab, end fraction, start text, space, k, i, l, o, m, e, t, e, r, end text

To convert smaller units to larger units we divide the number of smaller units by the purple conversion factor for the appropriate larger units.

Example: Converting meters to kilometers:

1, start text, space, m, e, t, e, r, end text, equals, start fraction, 1, divided by, start color #7854ab, 1000, end color #7854ab, end fraction, start text, space, k, i, l, o, m, e, t, e, r, end text

start color #ca337c, 7, end color #ca337c, start text, space, m, end text, equals, start fraction, start color #ca337c, 7, end color #ca337c, divided by, start color #7854ab, 1000, end color #7854ab, end fraction, equals, start color #ca337c, 7, end color #ca337c, divided by, start color #7854ab, 1000, end color #7854ab, equals, start color #11accd, 0, point, 007, end color #11accd, start text, space, k, m, end text
