Frequently Asked Questions
Which football field is used?
The American football field including end zones (109.728 m or 120 yards). For soccer/football pitches, we use the FIFA standard of 105 m. Both are shown in the results so you can pick your preference.
How tall is the Eiffel Tower exactly?
We use 324 metres, which includes the antenna. The structural height to the top floor is 300 m, but 324 m is the most commonly cited figure and what you would measure if standing at the base looking up.
Why these particular reference units?
These are commonly used in journalism and everyday speech to make abstract measurements relatable. "Three football fields long" or "twice the height of Big Ben" are phrases people understand intuitively.
Are the conversions exact?
The SI conversions (metres, feet, etc.) are exact. The fun unit comparisons use widely-accepted reference values. Some landmarks have variable dimensions (pitches vary, buildings are measured differently), so treat these as helpful approximations.
