铅笔公里用英语怎么说

"Pencil kilometers" is a colloquial Chinese term used to describe the length of text written by hand using a pencil, usually on a sheet of paper or a notebook. It is not an officially recognized term in English, and it is not commonly used in English-speaking countries.
The origin of the term "pencil kilometers" is not entirely clear, but it is thought to have originated from the idea that the length of text written by hand with a pencil can be quite long, similar to the distance of a kilometer. The term is often used to describe written work that is extensive and time-consuming, such as writing a novel or a thesis.
Here are some example sentences in English and their Chinese translations:
"I've written about 10 pencil kilometers for my thesis." (我为我的论文写了大约 10 铅笔公里。)
"It took me hours to write just a few pencil kilometers." (我花了几个小时才写了几铅笔公里。)
"He's a fast writer, he can write several pencil kilometers in a day." (他是个快速的写手，一天可以写几铅笔公里。)
Please note, this term is not commonly used in english-speaking countries, and pencil kilometer is usually not been translated by native speakers. The real way to express the meaning in english is the amount of writing, the length of written works, or volume of written text, etc.
