Duration x Length: Qual a diferença?

I would use duration to talk about time, and length to talk about size.

Cheguei a pensar nisso, mas em músicas, por exemplo, sempre se vê "Length" em vez de "Duration".

Na Internet eu vi isso:

Length is used to define distance or size whereas duration measures time period.

Actually length IS also used to define time period, as in: how long have you been waiting? So, while length may be used for either, duration is not used for distance.

Complemento:

- Sim, "duration" é específico para "duração de tempo". Veja as definições a seguir.

Duration: the length of time that something lasts or continues. [Oxford]
Duration: the length of time that something continues. [Longman]
Duration: the period of time during which something continues to happen or exist. [Macmillan]
Duration: the length of time that something lasts. [Cambridge]


- "Length" não se refere apenas ao tempo, fala de medidas em geral.
