Units explained
Terameter
A terameter is a metric unit of length equal to one trillion meters (1×10¹² m). It is rare in everyday use but appears in astronomy when expressing solar-system-scale distances in SI units.
The terameter uses the SI prefix tera- (from Greek teras, monster), adopted by the CGPM in 1960 to denote multiplication by one trillion (10¹²).
Terameters are occasionally used in astronomy to express distances on the order of Earth–Sun (~0.15 Tm or 1 AU) and outer-planet distances. The astronomical unit (AU) and light-hour are more common in practice.
SI prefix tera- adopted in 1960; the terameter is the standard SI prefix unit for distances comparable to inter-planetary scales but is less common than the AU in working astronomy.
Hectometer
A hectometer is a metric unit of length equal to one hundred meters (100 m). It is occasionally used in sports, agricultural surveying, and some European real-estate contexts.
The hectometer was defined alongside the meter when France adopted the metric system in 1795, using the SI prefix hecto- (from Greek hekaton, hundred) to denote multiplication by 100.
Hectometers appear in some sports contexts (the 100 m sprint is technically 1 hm), in agriculture (parcel sizes in some European nations), and in atmospheric science. Most contexts now use meters or kilometers instead.
Adopted in 1795 in France; ratified through the Metre Convention of 1875; remains a defined SI prefix unit although rarely used outside specialised contexts.
Terameter to Hectometer conversion formula
The relationship between terameters and hectometers:
To convert terameters to hectometers, multiply the value in terameters by 1e+10. To reverse, multiply hectometers by 1e-10.
How to use this converter
Type a value into the calculator. The result in hectometers updates as you type. Tap a quick value, copy the result with one click, or use the swap arrow to jump straight to the Hectometer to Terameter converter for the reverse direction.
Step-by-step: convert terameters to hectometers
- Write down the value in terameters (Tm).
- Multiply that value by the factor 1e+10.
- The product is the equivalent value in hectometers (hm).
- To reverse, multiply the hectometer value by 1e-10.
Worked examples
Example 1 — Convert 1 Tm to hm:
1 × 1e+10 = 1e+10 hm
Example 2 — Convert 100 Tm to hm:
100 × 1e+10 = 1e+12 hm
