To convert dm to meters: divide by 10. To convert dm to inches: multiply by 3.937.
1 dm = 0.1 m = 10 cm = 100 mm. One cubic decimeter (dm³) equals exactly 1 liter.
For example, 1 Decimeter (dm) = 1.000000e+17 Attometer (am).
| Decimeter (dm) | Attometer (am) |
|---|---|
| 0.1 | 1.000000e+16 |
| 0.5 | 5.000000e+16 |
| 1 | 1.000000e+17 |
| 2 | 2.000000e+17 |
| 5 | 5.000000e+17 |
| 10 | 1.000000e+18 |
| 25 | 2.500000e+18 |
| 50 | 5.000000e+18 |
| 100 | 1.000000e+19 |
| 500 | 5.000000e+19 |
| 1000 | 1.000000e+20 |
The decimeter is a unit of length equal to one tenth of a meter (10⁻¹ m), or 10 centimeters.
1 dm = 0.1 m = 10 cm = 100 mm. One cubic decimeter (dm³) equals exactly 1 liter.
To convert dm to meters: divide by 10. To convert dm to inches: multiply by 3.937.
The cubic decimeter (dm³ = 1 liter) is its most important practical application, linking length to volume.
The decimeter's greatest legacy is the liter — 1 liter is defined as exactly 1 dm³.
Rarely encountered, so people sometimes forget the conversion: 1 dm = 10 cm, not 100 cm.
Remember: deci = 10⁻¹. The decimeter's main utility is connecting length to volume via 1 L = 1 dm³.
The attometer is an extremely small unit of length equal to 10⁻¹⁸ meters, or one quintillionth of a meter.
1 am = 10⁻¹⁸ m = 10⁻⁹ nm = 0.001 fm. One meter contains 10¹⁸ attometers.
To convert am to meters: multiply by 10⁻¹⁸. To convert meters to am: multiply by 10¹⁸.
Measuring quark interaction distances and the scale of fundamental particle phenomena.
The effective size of a quark is estimated at less than 1 attometer — far smaller than a proton (~1,000 am across).
Confusing attometers with angstroms (Å = 10⁻¹⁰ m). Attometers are 100 million times smaller than an angstrom.
Think of the prefix chain: milli (10⁻³), micro (10⁻⁶), nano (10⁻⁹), pico (10⁻¹²), femto (10⁻¹⁵), atto (10⁻¹⁸).
