About this converter
Arabia covers 3,200,000 square km, about 1.3 million clear of the Southern Cone and Deccan at 1,900,000 each. Indochina and Alaska-Yukon at 1,500,000 each, Labrador at 1,400,000, Scandinavia at 800,000, Anatolia at 750,000, Iberia at 582,000 and Kamchatka at 270,000 follow. Peninsula edges follow broad physiographic cuts, not political lines. That choice matters most at Southern Cone, Deccan, Indochina and Alaska, where narrow cuts run hundreds of thousands lower and are noted per row.
How to use it
Pick two peninsulas and a unit in the top row. The three boxes below stay linked. Change any box and the other two update. Try Arabia against Iberia to see the five times gap. The bars below scale to Arabia so Kamchatka looks thin next to it. Switch the unit to square miles for US figures. Ratios are exact divisions of the land areas.
Anatolia at 750,000 ranks below Scandinavia at 800,000 despite draft table quirks. Broad versus narrow cuts split this table. Indochina narrow lists 1,200,000 beside broad 1,500,000. Scandinavia narrow lists 750,000 beside broad 800,000. Alaska-Yukon broad counts Yukon basin with the peninsula. Figures use broad cuts as primary with narrow noted.
