Frequently Asked Questions
-
What is a terameter used for?
-
A terameter is a very large SI-derived unit of length, equal to one trillion metres, used mainly to express distances on planetary and astronomical scales.
-
Where is the perch unit commonly found?
-
The perch is an old unit of length primarily used in historical surveying, land measurement, and is found in older legal and cadastral documents.
-
Why convert terameters to perch?
-
Users convert terameters to perch to interpret ancient land measurements or legal records using perch while relating these to very large distances expressed in terameters.
Key Terminology
-
Terameter [Tm]
-
An SI-derived unit of length equal to 10^12 metres, used for expressing extremely large distances such as those in astronomy.
-
Perch
-
A historic unit of length equal to 16.5 feet or about 5.0292 metres, formerly used in land surveying and property measurements.
