you could use the carbon-14 method or the uranium-lead method
the basic measure of length used to measure the thckness of a pin or leaf is in millimeter
either use feet or meters. use a tape measure or a meter stick (yard stick)
Miles
Light years are used to measure the great distances of space. One light year is about 5.86 trillion miles. This is the distance light travels in one year's time.
You would use a yardstick if you had to measure several feet.
To measure the distance of stars you have to measure by light years.
you use light years, and other units
Light years are used to measure distance from Earth to distant stars and planets.
Light years, parsecs, and kiloparsecs. Light years and parsecs are used to measure distances between neighbouring star system's, kiloparsecs are used to measure distances within a galaxy.

one way is how far light travles in a year , (light years)
Geologists measure geologic time in years.
Light Years.
Usually light-years, or parsecs.
Astronomers use the unit of measure "Light Years" to calculate the distance between pretty much anything in the Universe.
Seconds , minutes, hours, days, weeks months , years, etc.
They use lightyears and AU (Astronomical Units). They use kilometers, AU's and light years!! *Parsecs are also commonly used
