The diameter of the biggest lens or mirror that gathers light arriving from space. The diameter can be in mm, inches or metres.
Percent of an objects mass is expressed in terms of its weight. Percent of an objects volume is expressed in terms of its size.
which power of a telescope might be expressed as "0.5 seconds of arc"?
Get a bigger telescope. Resolution is proportional to the size of the telescope. But due to the atmosphere, there is a practical limit beyond which it makes no difference what the telescope size is.
The size of a telescope almost invariably refers to the size of it's objective lens, or mirror. It translates to how much light the telescope can gather, not "how big it can magnify", which is very secondary.
Particle size is typically characterized using the term "grain size." It refers to the measure of the size of individual particles in a material, commonly expressed in terms of diameter or average grain size.
To determine the size of a thread, you can use a thread gauge tool or a caliper to measure the diameter of the thread. The size is typically expressed in terms of the thread's pitch and diameter, which can help you identify the thread size.
This is normally expressed in terms of the radius: area = pi x radius2.This is normally expressed in terms of the radius: area = pi x radius2.This is normally expressed in terms of the radius: area = pi x radius2.This is normally expressed in terms of the radius: area = pi x radius2.
The size of a reflecting telescope is typically indicated by its aperture, which is the diameter of the primary mirror. Aperture size plays a crucial role in determining the light-gathering ability and resolving power of the telescope.

43 over 86, when expressed in lowest terms, is 1 over 2.
It gathers more light than a refractor type of telescope can, of the same size.
