I would either use Micrometers or Millimeters
The head or the point of the pin? I would measure the head in millimeters and the point of the pin in micrometers.
0.001 inch, how many micrometers would this be?
The millimeter should be sufficient. If you want greater precision, measure with micrometers. A nickel made in the USA is about 2 millimeters thick, which is equivalent to 2,000 micrometers. However, keep in mind that the precise thickness will vary from nickel to nickel, depending on the amount of wear.
1 micrometer = 1.0 × 10-9 kilometers So, 78 micrometers = 0.000000078 kilometers
They are approximately 60 micrometers by 20 micrometers, so as a ratio it would be 3:1.
You could measure with Kilometers, Deckameters,hectometers,meters,decimeters,centimeters,millimeters, or micrometers. To give you an idea, one centimeter is equal to 2.54 inches. There are about three feet in one meter.
I would use micrometers.
it would be 250 millimeters
it would be 100 millimeters
The same reason metres are used to measure houses instead of miles. One is of the right size at that scale, the other is so large all measurements would be in very small decimals.
A micrometer is ten thousand times shorter than a centimeter, hence, 2.5 centimeters = 25,000 micrometers.
mm stands for millimeters. So it would be two millimeters. There are 25.4 millimeters in an inch..
There are ten mm in a cm. The answer would be 314 millimeters.
Millimetres or micrometers
There are 10 millimeters to every 1 centimeter. So, there would be more millimeters in a given length than centimeters. To increase a number you would multiply.
The prefix milli- means "one thousandth" so to convert 4 m to millimeters you would multiply by 1000. 4 m = 4000 millimeters.
Multiply kilometers by one million to get millimeters.
Multiply the length in inches by 25.4 to get millimeters.
1 teaspoon is 5 millimeters so 9 millimeters... that would be 1.8 teaspoon.
1900 millimeters. 1900 millimeters converted to decimeters would be 19.00 decimeters.
Multiply by 10. There are 10 millimeters in one centimeter. So if you have 70 centimeters you would have 700 millimeters.
If you mean to say "How many millimeters in an inch?" (Millimeters, not mileometers) then the answer would be 1 inch is 25.4 millimeters.
The area would be 12*18, or 216 square millimeters.
