How to Convert Attometer to Picometer
To convert am to meters: multiply by 10⁻¹⁸. To convert meters to am: multiply by 10¹⁸.
1 am = 10⁻¹⁸ m = 10⁻⁹ nm = 0.001 fm. One meter contains 10¹⁸ attometers.
For example, 1 Attometer (am) = 0.000001 Picometer (pm).

About Attometer (am)
Definition
The attometer is an extremely small unit of length equal to 10⁻¹⁸ meters, or one quintillionth of a meter.
Mathematical Relationship
1 am = 10⁻¹⁸ m = 10⁻⁹ nm = 0.001 fm. One meter contains 10¹⁸ attometers.
Conversion Formula
To convert am to meters: multiply by 10⁻¹⁸. To convert meters to am: multiply by 10¹⁸.
Practical Applications
Measuring quark interaction distances and the scale of fundamental particle phenomena.
Interesting Facts
The effective size of a quark is estimated at less than 1 attometer — far smaller than a proton (~1,000 am across).
Common Mistakes
Confusing attometers with angstroms (Å = 10⁻¹⁰ m). Attometers are 100 million times smaller than an angstrom.
Educational Tips
Think of the prefix chain: milli (10⁻³), micro (10⁻⁶), nano (10⁻⁹), pico (10⁻¹²), femto (10⁻¹⁵), atto (10⁻¹⁸).
About Picometer (pm)
Definition
The picometer is a unit of length equal to 10⁻¹² meters, or one trillionth of a meter.
Mathematical Relationship
1 pm = 10⁻¹² m = 0.01 Å = 1,000 fm. One nanometer equals 1,000 picometers.
Conversion Formula
To convert pm to meters: multiply by 10⁻¹². To convert pm to angstroms: divide by 100.
Practical Applications
Expressing covalent bond lengths (e.g., C–C bond ≈ 154 pm), atomic radii, and crystal lattice spacings.
Interesting Facts
The hydrogen atom has a radius of about 53 pm (the Bohr radius), while a carbon-carbon single bond is about 154 pm long.
Common Mistakes
Mixing up picometers and nanometers — remember 1 nm = 1,000 pm. Some sources still use the deprecated angstrom.
Educational Tips
Think of pm as the natural unit for atoms: most atomic radii fall between 30 pm and 300 pm.
