To help compare different orders of magnitude this page lists lengths between 10⁻³ m and 10⁻² m (1 mm and 1 cm).

Distances shorter than 1 mm

• 1.0 mm — 1/1000^th of a metre
• 1.0 mm — 0.039 inches or 5/127 (exactly)
• 1.0 mm — side of square of area 1 mm²
• 1.0 mm — edge of cube of volume 1 mm³
• 1.0 mm — diameter of a pinhead
• 1.5 mm — length of average flea
• 2.54 mm — distance between pins on old DIP (dual-inline-package) electronic components
• 5 mm — length of average red ant
• 5.56 x 45 mm NATO — standard ammunition size
• 7.62 x 51 mm NATO — common military ammunition size
