Store description excerpt
[Please note first] This app shows no maps and no land prices. It cannot work out an area for you either, since a phone has no sensor for that. You enter an area you already know, and it is set against sizes that are already fixed. Names shown are the trademarks of their respective owners; this app is not affiliated with any of them. ────────── 🟩 Area Comparison — how big is that, really? "510,000 square metres" tells you almost nothing on its own. That is Tokyo Disneyland, and it comes to 10.9 Tokyo Domes. Enter one area and compare it against 27 things, from a sheet of A4 paper to the surface of the Earth. ■ Two ways to use it ▪ About this big — the five things closest to your area, smallest first ▪ How many? — how many of each of the 27 things your area comes to "About this big" shows the nearest five; the full list of 27 sits just below it. The same entries serve both tabs. ■ Twenty-seven things A4 paper (0.671 sq ft, or 0.06237 m²), a tatami mat, one tsubo, a table tennis table, a six-mat room, a parking space, badminton, volleyball, tennis and basketball courts, a 50 m pool, an American football field, a football pitch, the Tokyo Dome, Tokyo Disneyland, the Imperial Palace, inside the Yamanote Line, the 23 wards of Tokyo, Lake Biwa, Singapore, Kagawa, Tokyo, Hokkaido, Japan, Russia, and both the land and the whole surface of the Earth (510,100,000 km²). Tap any row to load its area. ■ The Tokyo Dome, a Japanese unit of area In Japan, large areas are quoted in Tokyo Domes much as football fields are used elsewhere. The figure counted is 46,755 m², the building footprint with the roof on; the playing field alone is about 13,000 m², a factor of 3.6 smaller. ■ One tsubo is exactly two tatami mats One ken is 6 shaku, or 20/11 m, and a square of that side is one tsubo: 400/121 m². A tatami mat is 6 by 3 shaku, or 200/121 m² — exactly half. Enter 400 m² and the tsubo row reads exactly 121. ■ Exact figures and ranges are kept apart Courts and pools are exact, their size fixed by the rules of the sport: a doubles tennis court is 23.77 by 10.97 m, or 260.7569 m². Parking spaces and football pitches vary, so a range is shown as well as a typical figure. The Laws of the Game allow 90 to 120 m by 45 to 90 m. 105 by 68 m, or 7,140 m², is recommended for international matches, and the range in the list, 6,400 to 8,250 m², is what those matches allow: 100 to 110 m by 64 to 75 m. Ranges are for reading only; comparisons use the typical figure. ■ Readable at every scale The same screen shows "0.671 sq ft" and "510,100,000 km²". Each row gives the thing's area in its own unit. sq ft → m² → km² ■ Good for ▪ Making sense of a figure in square kilometres from the news ▪ Putting the size of a room into everyday terms ▪ Any moment you see a number and wonder whether it is big ■ Things worth knowing (included in the app) ▪ The Tokyo Dome of "so many Tokyo Domes" is the building footprint, 46,755 m², not the playing field ▪ One tsubo is ex
