You measure a house fly in millimeters
a scale factor of 4.5 is your answer
Millimeter wavelengths are short frequency radio waves astronomers use because they can see gases and other phenomena not visible in visible light. MM wavelengths are usually used where the air is dry so water vapor can't scatter the waves.
to play
you use it on move tutors to teach your Pokemon moves
Depending how small it is, you could use the meter, the millimeter, the micron (= micrometer), the nanometer, etc. The meter is approximately the height of a child; the millimeter is 1/1000 of that, the micron is a millionth of a meter, the nanometer is a billionth of a meter.
Zero degrees on the Celsius scale equals thirty two degrees on the Fahrenheit scale.
No, there cannot be a zero in any scale factor.
The scale would be 1:240
1/8 equals 1 foot or 1inch equals 8 feet ect.
For visible light, the nanometer (nm) is usually used. For other wavelengths of EM waves, other prefixes can be used with the meter; for example meter, kilometer, millimeter, femtometer, etc.
Millimeter
I use a scale, my kitchen scale if less than 10 pounds, bathroom scale if over 10 pounds
nanometer
A square nanometer.
yes
You could use any metric unit of length: e.g. meter, kilometer, decameter, megameter, femtometer, nanometer, micrometer, millimeter, centimeter. However it would probably be most logical and easiest to use the kilometer.
