Is there anything smaller than a millemeter

The micro-, nano-, picto-, and femto- are all prefixes that indicate sizes smaller than the milli-.

how do i know how much a mile is?

This is something that you will probably want to memorize. A mile is 5280 feet. Once you have that in your memory, you can then use math to determine how many yards a mile is and all sorts of other measurements.

how many yards are in 14 miles

the answer is 24640 because of 1760 yards in a mile and 1760 x 14 = 24640

Thank You! this is really helpful but is there a faster way or less confusing way

I find the metric system is easier and faster, because its all based on tens

how much is three yards

3 yards in meters is 2.7432m. 3 yards in feet is 9ft.

What unit of measure would you use to measure the length of a soda can? Inches, centimeters, or millimeters?

Inches, because cm's is too small and mm's is _WAY_ too small

Review the size of inches, feet, yards, and miles and how to convert between them. Then, try some practice problems.

Summary of customary units of distance

Inches	Feet	Yards	Miles
$63, 360$ ‍	$5, 280$ ‍	$1, 760$ ‍	$1$ ‍
$36$ ‍	$3$ ‍	$1$ ‍	$\frac{1}{1, 760}$ ‍
$12$ ‍	$1$ ‍	$\frac{1}{3}$ ‍	$\frac{1}{5, 280}$ ‍
$1$ ‍	$\frac{1}{12}$ ‍	$\frac{1}{36}$ ‍	$\frac{1}{63, 360}$ ‍

What is distance?

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

In the US customary system of measurement, the most common units of distance are inches, feet, yards, and miles.

How big are customary units of distance?

The length of a quarter is about

1

inch.

The length of a man's shoe is about

1

foot.

The length of a guitar is about

1

yard.

The length of a runway at a large airport is about

1

mile.

Converting larger units to smaller units

1 foot = 12 inches

1 yard = 3 feet

1 yard = 36 inches

1 mile = 1760 yards

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 feet to inches

1 foot = 12 inches

5 feet = 5 \times 12 = 60 inches

Converting smaller units to larger units

1 inch = \frac{1}{12} foot

1 foot = \frac{1}{3} yard

1 yard = \frac{1}{1760} mile

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

Example: Converting inches to feet

1 inch = \frac{1}{12} foot

72 inches = \frac{72}{12} = 72 \div 12 = 6 feet

Example: Converting yards to miles

1 yard = \frac{1}{1760} mile

17,600 yards = \frac{17,600}{1760} = 17,600 \div 1760 = 10 miles

  millimeter = 1/1,000 meter.
  micrometer = 1/1,000,000 meter.
  nanometer = 1/1,000,000,000 meter.
  
  and there is no limit to how many units there should be. whenever we find a length in the real world that we need to express a lot of times and we don't have a unit that's close to this length, we can create a new unit of length.
