Durante el siglo <span style="font-variant:small-caps;text-transform:lowercase">XIX</span> y principios del <span style="font-variant:small-caps;text-transform:lowercase">XX</span> esta teoría jugó un papel relevante en los debates sobre si Gran Bretaña y Estados Unidos debían o no adoptar el <a href="/wiki/Sistema_m%C3%A9trico_decimal" title="Sistema métrico decimal">sistema métrico decimal</a>.<sup id="cite_ref-4" class="reference separada"><a href="#cite_note-4"><span class="corchete-llamada">[</span>4<span class="corchete-llamada">]</span></a></sup> </p><p>La teoría de Taylor y Smyth tuvo eminentes defensores y detractores pero a finales del XIX ya había perdido casi todo el apoyo de la ciencia establecida.

Cuando Petrie fue a Egipto in 1880 para realizar nuevas mediciones, descubrió que la pirámide era varios pies más baja de lo que inicialmente se creía, incluyendo el sillar de coronamiento perdido. Esto socavó tanto la teoría que Petrie la rechazó, al escribir "no hay ningún ejemplo auténtico, que pueda superar escrutinio alguno, del uso o existencia de una medida tal que la "pulgada piramidal", o de un codo de 25,025 pulgadas británicas"<sup id="cite_ref-5" class="reference separada"><a href="#cite_note-5"><span class="corchete-llamada">[</span>5<span class="corchete-llamada">]</span></a></sup> . </p><p>El valor de 1,00106 pulgadas británicas se calcula como la 1/500.000.000 parte del diámetro de la tierra en los polos. </p> <div class="mw-heading mw-heading2"><h2 id="Referencias">Referencias</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Pulgada_piramidal&action=edit&section=2" title="Editar sección: Referencias"><span>editar</span></a><span class="mw-editsection-bracket">]</span></span></div> <div class="listaref" style="-moz-column-count:2; -webkit-column-count:2; column-count:2; list-style-type: decimal;"><ol class="references"> <li id="cite_note-1"><span class="mw-cite-backlink"><a href="#cite_ref-1">↑</a></span> <span class="reference-text">J.
