ASOS → Nike
Different brands. Different sizes. Different countries.
A Medium in ASOS is not the same as a Medium in Nike — and your size changes again depending on whether you're shopping in the US, UK, EU, or Asia. WhatSize handles both.

Why ASOS and Nike sizes don't match
There are no international standards for clothing sizes. ASOS and Nike each define their own measurements for sizes like "Medium" or "Size 10."
It gets worse across regions. A ASOS Medium in the US is a different measurement to a ASOS Medium in Europe or Asia. Same brand, different country, different size.
WhatSize handles both — brand differences and regional differences — using the actual centimetre data.
