1 cm of 30.5 cm is a ratio - a pure number. There are no picometres in a number.
I will use the volume of a sphere formula and the density of gold to find this answer. The radius of gold is 144 picometers. 13 inches (2.54 centimeters/1 in)(1 meter/100 centimeters)(1012 picometers/1 meter) = 3.30 X 1011 picometers --------------------------------/2 = 1.65 X 1011 picometers in radius of this sphere =================================So, that means that the radius of the gold would be as to the sphere..., 1.65 X 1011 picometers/144 picometers = 1.15 X 109 picometers of gold radius here =======================================================( final answer )
There are 10 000 micrometres in 1 centimetre
1 meter = 1,000,000,000,000 picometers = 1012 picometers = 1 trillion picometers
10 millimeters = 1 centimeter 305 millimeters = 30.5 centimeters
1 meter=1,000,000,000,000 picometers
There are 1,000,000,000,000 picometers in 1 meter.
1 meter=1,000,000,000,000 picometers
1 picometer = 0.000000001 millimetres
0.0004 = 4 x 10-41 pico... = 1 x 10-124 x 10-4/1 x 10-12 = 400 million of them
There are 1 trillion picometers in a meter. Therefore, 400 picometers is equal to 0.0000004 meters.
1 meter = 1 000 000 000 000 picometers
One nanometer is equal to 1,000 picometers.
