• Typical capacity: 800-1200 mAh
• Used in small electronic devices like remote controls and wall clocks

The standardized size of AAA batteries, including their 2 cm diameter when paired, allows for consistency in device design across manufacturers. This standardization is a key factor in the ubiquity and interchangeability of these power sources.

6. A Cherry Tomato

These bite-sized flavor bombs typically measure about 2-3 cm in diameter. Cherry tomatoes are a testament to nature’s ability to pack big taste into small packages:

• High in vitamins A and C
• Rich in lycopene, an antioxidant
• Versatile in salads, cooking, and snacking

The compact size of cherry tomatoes makes them ideal for snacking and adding bursts of flavor to dishes without overwhelming other ingredients. Their 2 cm size also makes them perfect for practical measurements in the kitchen.

7. An SD Card

Standard SD cards measure 32 mm x 24 mm, with the shorter side being close to our 2 cm mark. These tiny storage devices showcase how technology allows us to pack vast amounts of data into small spaces:

• Storage capacity ranging from 128 MB to 128 GB or more
• Used in cameras, phones, and other portable devices
• Transfer speeds up to 300 MB/s in high-end models

The compact size of SD cards, with one dimension close to 2 cm, allows for their use in a wide range of portable devices. This standardized size has revolutionized data storage and transfer in the digital age.
