Kubera ko ari kimwe mu bikoresho nyamukuru mu bijanye no gupima amashanyarazi, ugutegura ibipimo vy’amashanyarazi vy’inzira imwe-bifitaniye isano cane n’iterambere ry’ikoreshwa ry’amashanyarazi mu kibano c’abantu. Kuva amashanyarazi akoreshwa cane-mu mpera z'ikinjana ca 19, ukuza n'ugutera imbere kw'ibipimo vy'amashanyarazi ntivyateje imbere gusa ubuhinga bwo gucunga inguvu ariko kandi vyaragize ico bikoze cane ku buryo amashanyarazi akoreshwa mu bikorwa vy'ubuhinga bwa none no mu buzima bwo mu nzu.
Mu myaka ya 1880, n’uguteza imbere uburyo bwa Edison bwo gutanga amashanyarazi akoresheje amashanyarazi ataco akora, ni ho haje ibikoresho vya mbere vyo gupima amashanyarazi. Mu 1889, injeniyeri w’Umudagi yitwa Hermann Aron yarahinguye igipimo c’inguvu z’umuyagankuba gishingiye ku ngingo ngenderwako y’ubuhinga bw’umuyagankuba, kikaba cari giharura mu buryo butaziguye inguvu zikoreshwa mu gupima ukuntu ivyuma bigenda mu mazi. Ariko rero, ico gikoresho cari gifise ubushobozi buke bwo gukora neza kandi kikaba cari gikomeye cane mu bijanye no kugibungabunga, ivyo bikaba vyatuma kigora gukundwa cane. Mu myaka ya 1890, ukuza kw’imirongo y’amashanyarazi ahinduka kwatumye habaho igipimo c’inguvu z’amashanyarazi gikoreshwa n’amashanyarazi. Mu mwaka w’1896, umunyabwenge w’umunyamerika Elihu Thomson yarahinguye igipimo ca mbere c’umuyagankuba w’inzira imwe-y’ubudandaji. Ubwo buhinga, bukoresheje ingingo ngenderwako y’uguhindukiza igipande c’aluminiyumu gikoreshwa n’ububasha bw’umuyagankuba buhinduka, bwatumye umuntu ashobora gupima ata guca ku ruhande inguvu z’umuyagankuba. Kubera ko ubuhinga bwabwo bworoshe kandi bwizigirwa cane, bwacitse umuti w’ingenzi kw’isi yose mu gice ca mbere c’ikinjana ca 20.
Mu mpera z’ikinjana ca 20 hagati -kugeza -, ubuhinga bushasha bwatumye habaho ubuhinga bushasha bwo gupima umuyagankuba. Mu myaka ya 1970, gukoresha ubuhinga bwo gupima umuyagankuba bushingiye ku buhinga bwa none vyatumye buhorobuhoro ibipimo vy’umuyagankuba vy’ubuhinga bwa none bishobora gusubirira buhoro buhoro ibipimo vy’amashanyarazi vya kera, bikaba vyatuma umuntu ashobora gupima neza cane kandi ntashobora gushikirwa n’ingorane. Mu mpera z’ikinjana ca 20, ugushiraho ubuhinga bwa microprocesseur kwatumye habaho ubushobozi bwo gupima amashanyarazi bufise ubushobozi bwo kubika amakuru no guhanahana amakuru kure, ivyo bikaba vyatumye habaho umushinge wo gutegura amashanyarazi y’ubwenge. Kuva mu kinjana ca 21, ibipimo vy’amashanyarazi vy’inzira imwe-vyagiye biragenda buhoro buhoro bija mu gukoresha ubuhinga bwa none no gukorana n’abandi, bishigikira ibipimo vy’inzira zibiri n’ugukurikirana igihe nyaco-, bishitsa ivya nkenerwa vyo kuronka inguvu zitandukanye no gucunga uruhande rw’abakoresha.
Kuva ku bikoresho vy’ubuhinga gushika ku bikoresho vy’ubwenge, amateka y’ibipimo vy’amashanyarazi vy’inzira imwe-yerekana ukuntu abantu bakurikirana ata guhagarika umutima gukoresha neza inguvu. Ubu, si igikoresho co gutanga amafaranga y’amashanyarazi gusa, ariko kandi ni urudodo rudakenewe cane muri Internet y’inguvu, rukaba ruguma rutanga infashanyo y’ubuhinga bwo guhindura inguvu kw’isi yose.
