1 Meter = 1000 Millimeters
multiply meters by 1,000 to get mullimeters
European system is in Tenths Hundreds Thousands all multiplied/divided by multiples of 10.
Micrometer 0.000001 1 millionth of a meter
Millimeter 0.001 1 thousandth of a meter
Centimeter 0.01 1 hundredth of a meter
Decimeter 0.1 1 tenth of a meter
Decameter 10 meters
hectometer 100 meters
kilometer 1000 meters
megameter 1 million meters
C centimeter .01
K Kilometer 1000
M Millimeter .001
Units must be consistent
First, we shall convert feet to inches or inches to feet.
It is better to have the same unit while solving these kind of problems.
Let's convert feet to inches.
12 inches make a foot.
In other words, 1 foot = 12 inches.
So, 6.56 feet times 12 inches per foot gives us 78.72 inches.
(6.56)*12 = 78.72 inches
Now, divide that by 9.0 inches, which yields 8.75.
(78.72)/9.0 = 8.74666...
78.72/9.0 is 656/75.
A red cent was a paper token, colored red. During WWII they were used for change in return for rationing coupons.
"not one red cent" = "not a penny"
Boat and aircraft speed is measured in Knots. Both mph and knots is a measurement of distance that is traveled over a certain period of time. 1 knot = 6076 feet per hour or 1 nautical mile per hour 1 mph = 5280 feet per hour or 1 mile per hour
According to http://mathworld.wolfram.com/RadiusVector.html the radius vector (often written as r hat, or the letter r with a carrot ^ over it) is just the distance from the origin to the point of interest.
So the magnitude is the distance between the point and the origin, and the direction is the direction from the origin to the point.
