  • differences Is it "flotation" or "floatation"? English

    Some results for floatation and flotation with various related_terms are below. M = millions of hits. k = 1000's of hits. e.g. "Australia 420 k / 10.9 M" = 420,000 hits for floatation and Australia, 2.29 million hits for Australia and flotation. Very obviously this method has methodological deficiencies, but it is also demonstrably useful.
