O QUE SIGNIFICA DIMENSIONLESS EM INGLÊS
Quantidade sem dimensão
Na análise dimensional, uma quantidade ou quantidade sem dimensão da dimensão um é uma quantidade sem uma dimensão física associada. É, portanto, um número "puro" e, como tal, tem sempre uma dimensão de 1. As quantidades sem dimensões são amplamente utilizadas em matemática, física, engenharia, economia e na vida cotidiana. Numerosas quantidades bem conhecidas, como π, e e φ, são adimensionais. Em contrapartida, as quantidades não dimensionais são medidas em unidades de comprimento, área, tempo, etc. As quantidades sem dimensões são muitas vezes definidas como produtos ou proporções de quantidades que não são adimensionais, mas cujas dimensões se cancelam quando seus poderes são multiplicados. Este é o caso, por exemplo, com a tensão de engenharia, uma medida de deformação. É definido como mudança de comprimento, dividido pelo comprimento inicial, mas como essas quantidades têm dimensões L, o resultado é uma quantidade sem dimensão.
definição de dimensionless no dicionário inglês
A definição de adimensional no dicionário é sem unidades físicas. Outra definição de adimensional é ter, ou parece não ter variáveis convencionalmente mensuráveis, como comprimento, largura, altura ou diâmetro.

I find my earliest memories covering the anachronistic features of a previous incarnation. Clear recollections came to me of a distant life, a yogi amidst the Himalayan snows. These glimpses of the past, by some dimensionless link, also afforded me a glimpse of the future.
