1 picometer = 1.0 × 10-12 meters
A picometer is 10-12 of a meter, and a centimeter is 10-2 of a meter. So, 250 picometers is 2.5x10-8cm.
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 )
1 picometer is one one-trillionth of a meter. 1 centimeter is one one-hundredth of a meter. There are 10,000,000,000 picometers in 1 centimeter.
One nanometer is equal to 1,000 picometers.
There is one meter in a meter...
1 meter=1,000,000,000,000 picometers
1 meter = 1,000,000,000,000 picometers = 1012 picometers = 1 trillion picometers
1 meter=1,000,000,000,000 picometers
1 meter = 1 000 000 000 000 picometers
1 meter = 1 000 000 000 000 picometers
There are 1 trillion picometers in a meter. Therefore, 400 picometers is equal to 0.0000004 meters.
A picometer is 10-12 of a meter, and a centimeter is 10-2 of a meter. So, 250 picometers is 2.5x10-8cm.

I assume you mean laid end to end. 1 meter = 1 X 10-12 in picometers. A copper atom is 128 picometers in radius, which means it is 256 picometers in diameter, long and end to end laid out. so, 256 picometers/1 X 10-12 = 2.56 X 1014 atoms in one meter laid end to end ---------------------------------------------------------------
There are 1,000,000,000,000 picometres in one metre.
1 picometer is one one-trillionth of a meter. 1 centimeter is one one-hundredth of a meter. There are 10,000,000,000 picometers in 1 centimeter.
Ok let's see if this is the right path. A very broad question. 1 Meter = 10 Decimeters 1 Meter = 100 Centimeters 1 Meter = 1000 Millimeters 1 Meter = 100000000 Picometers 1 Meter = 1000000000 Nanometers
