Banana Calculator:

the Standard Internet (SI) Unit

Take the boring out of measurement!

Let’s be honest: standard unit converters are dull. They take one abstract number and turn it into another abstract number. Knowing that something is 1,000 meters long is useful, but does it really help you picture the scale?

I wanted to build a tool that didn't just convert numbers, it actually helped people visualize them. I wanted to answer the questions that standard calculators can't, like: 'How many giraffes tall is the Empire State Building?' or 'How many Olympic swimming pools would fit inside the Grand Canyon?'

What started as a nod to the classic internet meme of using a "banana for scale" has grown into a comprehensive, powerful, and slightly absurd conversion tool.

It is designed to help journalists, students, teachers, writers, and the endlessly curious make sense of the world's varied scales. It works seamlessly across four categories:

• Length: Convert boring miles and kilometers into lengths of string, London buses, sports fields, or even the distance to the moon.
• Weight: Forget tons and kilograms; measure mass in terms of blue whales, African elephants, the Golden Gate Bridge, or common house mice.
• Volume: Visualize space using cans of coke (US and EU standards), oil barrels, teaspoons, or even the volume of the Earth itself.
• Area: Compare sizes ranging from nano SIM cards, postage stamps, tennis courts or Vatican City right up to Australia and even the surface of the Sun.

Handling the Huge (and the Tiny)

I didn't just want fun units; I wanted a serious math engine under the hood. Most online tools fail when dealing with astronomical or microscopic scales. The Banana Calculator was built specifically to handle these extremes, providing clear, readable results for tiny fractions right up to mind-blowingly massive numbers such as Quadrillions, Decillions, and Vigintillions.

It’s math made tangible. Go give it a try.
