A scale. A newton metre.
The answer depends on the scale but the SI unit is a metre.
Mesuring a metre.
There can be no equivalence. A square is a shape of unspecified measure while a square metre is a square whose sides are a metre each.
Frequency Metre is a device that displays the frequency of waves/strength of waves: may it be Audio/Radio waves. It is usually analogue but nowadays they come in digital. Mostly frequency metre is used in transmitting stations to find the frequency strength. Also, these metres are used in recording studio for knowing audio strength. The frequency metre used in a transmitter is usually have: a scale that shows DB and the metre is directly coupled to the antenna. Moreover, nowadays, the digital metre shows: db, frequency, antenna voltage etc in a single dial where as there used to be several dials/metres for each of these. One can find a frequency metre in a HAM setup. Actually this device is a type of Ammetre and volt metre. Dhinakar Rajaram Iyer rdhinakar@aol.in
A metre scale measures upto one millimetre.In order to measure lengths less than one millimeter a vernier callipers or screw gauge is used.
Are we talking nanometres? 1 nanometre is one BILLIONTH of a metre. Engineers choose a scale of measure that is proportionate to what they are measuring. Nanometres on a subatomic scale, light years on a cosmic scale. Certainly you can convert one to the other but it is of little use. To convert nm to feet. Feet to metre multiply by 0.3048. A nanometre is one billionth of that. One billion in numbers is 1,000,000,000.
They are metre, kilogram and cubic metre respectively. However, the litre (=0.001 cubic metre) is also used for volumes.
metre
The scale used to measure the strength of an earthquake is called the Richter scale
The US spelling is meter. The French spelling used in Canada is metre.
