Conversions:
* 1 inch = 25.4 mm
* 1 foot = 12 inches
* 1 yard = 3 feet
Calculations:
1. Millimeters to inches: 55 mm / 25.4 mm/inch = 2.165 inches
2. Inches to feet: 2.165 inches / 12 inches/foot = 0.1804 feet
3. Feet to yards: 0.1804 feet / 3 feet/yard = 0.0601 yards
Therefore:
* 55 mm is approximately 0.1804 feet
* 55 mm is approximately 0.0601 yards
