Nanometers

A nanometer is equal to 10^-9 (Billionth) meters. It’s usually bigger than an atom. 1000 nanometers is a micrometer. Basically shorter than everything. The symbol is nm.

Fun fact on nanometers

100,000 nanometers (100 micrometers) is the thickness of a sheet of paper.

Micrometers to decimeters

Micrometers

A micrometer is equal to 10^-6 (millionth) meters . Not everything is bigger than 1 micrometer. 1000 micrometers make 1 millimeter. Symbol is um (I can’t use the right letter due to restrictions).

Millimeters

A millimeter is equal to 10^-3 (thousandth) meters. Not everything is bigger than an a millimeter. 1000 millimeters is equal to 1 meter. Symbol is mm. It’s about the size of the needle thickness on a pin 📌.

Centimeters

A centimeter is equal to 10^-2 (hundredth) meters. It’s equal to 10 millimeters. Not everything is bigger than a centimeter. 2.54 centimeters is 1 inch. Symbol is cm.

Decimeters

A decimeter is equal to 10^-1 (tenth) meters. It’s equal to 10 centimeters or 100 millimeters. A lot of things is about 1 decimeter. Symbol is dm.

Meters to Megameters

Meter

A meter is the standard unit for length, height and distance. It’s equal to 40 inches (not exact but super close). A lot of things can be about a meter. The meter stick is used to measure stuff in meters. Symbol is m.

Dekameters

A dekameter is equal to 10 meters or 100 decimeters or 1000 centimeters or 10000 millimeters. The symbol is dam.

Hectometer

A hectometer is equal to 100 meters or 10 dekameters or 1000 decimeters or 10000 centimeters or 100,000 millimeters. The symbol is hm.

Kilometer

A kilometer is equal to 1000 meters or 10 Hecto meters or 100 dekameters or 100000 centimeters or 1,000,000 millimeters. Kilometers are often seen on signs in non imperial countries. The symbol is Km.

Megameter

A megameter is equal to 1,000,000 meters. It’s a far distance. People could possibly run 🏃‍♂️ 1 megameter in a year. It’s equal to 1000 kilometers. Symbol is Mm.
