The millimeter is a unit of length equal to one thousandth of a meter (10⁻³ m), or one tenth of a centimeter.
1 mm = 0.001 m = 0.1 cm = 1,000 µm. There are 25.4 mm in one inch.
To convert mm to inches: divide by 25.4. To convert inches to mm: multiply by 25.4.
Engineering drawings, screw thread specifications, rainfall measurements, paper thickness, and small component dimensions.
Standard A4 paper is 210 × 297 mm. A credit card is about 0.76 mm thick.
Confusing mm with cm on rulers — each cm mark has 10 mm divisions. Also, misreading calipers by one mm.
A dime is about 1.3 mm thick — use it as a quick visual reference for millimeter scale.
The mile is a unit of length equal to 5,280 feet, 1,760 yards, or exactly 1,609.344 meters.
1 mi = 5,280 ft = 1,760 yd = 1,609.344 m = 1.609344 km.
To convert miles to km: multiply by 1.60934. To convert km to miles: multiply by 0.621371.
Highway distances, speed limits (mph), running races (1-mile run), and property boundary descriptions.
A 4-minute mile was once thought impossible. Roger Bannister broke the barrier in 1954 with a time of 3:59.4.
Confusing statute miles with nautical miles (1 nmi = 1.852 km vs 1 mi = 1.609 km). They're different units.
Quick km↔mi: Fibonacci numbers approximate the ratio! 5 mi ≈ 8 km, 8 mi ≈ 13 km, matching the 1.6 ratio.
