To compare the lengths of one yard, one kilometer, one meter, and one inch, we can convert them all to the same unit, such as inches:
- 1 yard = 36 inches
- 1 kilometer = 39,370.1 inches
- 1 meter = 39.37 inches
- 1 inch = 1 inch
Now, we can see the lengths:
- 1 yard = 36 inches
- 1 kilometer = 39,370.1 inches
- 1 meter = 39.37 inches
- 1 inch = 1 inch
The shortest length among these is one inch.
