It's just a skill. You do need some visualization ability, but pick a mental yardstick. I used a 6ft tall person. Then just picture them laid end to end to ballpark a certain dimension.
The rest is just some quick arithmetic. Then as you end up practicing it over time, it becomes easier until you're just like "yeah, that's like 100' or something".
The place you live in makes an easy yardstick.
a hundred what?
' is a shorthand for feet in freedom-units notation. " is inches.
thanks
