 | It typically has six and a half octaves (46 or 47 strings), weighs about 80lb (36 kg), is approximately 6 ft (1.8 m) high, has a depth of 4 ft (1.2 m), and is 21.5 in (55 cm) wide at the bass end of the soundboard. |
| The notes range from three octaves below middle C (or the D above) to three and a half octaves above, usually ending on G. The tension of the strings on the sound board is roughly equal to a ton (10 kilonewtons). |

| The tonne may also be referred to by the strictly SI term megagram, symbol Mg. |
| Like grams and kilograms, tonnes have also given rise to a force unit of the same name: 1 tonne-force = 9.80665 kilonewtons (kN), a unit also often called simply "tonne" or "metric ton" without identifying it as a unit of force. |
| Note that it is only the tonne as a unit of mass which is accepted for use with SI; the tonne-force or metric ton-force is not acceptable for use with SI. |
