Izinhlelo ezahlukene zamayunithi
Singaguqula amayunithi kusuka ohlelweni olulodwa lwamayunithi kuya kolunye, njengokusuka ohlelweni lwaseBrithani kuya ohlelweni lwamazwe ngamazwe , noma ngokuphambene nalokho. Isibonelo, uma silinganisa ubude betafula sisebenzisa irula ngamasentimitha (uhlelo lwaseBrithani) futhi sifuna ukuveza ubude ngamamitha (uhlelo lwamazwe ngamazwe), singaguqula isilinganiso kusuka kumasentimitha kuya kumamitha. Lokhu kuguqulwa kungenziwa kusetshenziswa isici sokuguqula.
Uhlelo olufanayo lwamayunithi
Singaguqula futhi amayunithi ngaphakathi kohlelo olufanayo lwamayunithi, njenge-International System of Units. Isibonelo, siyazi isisindo sento ngamagremu (g) futhi sifuna ukuyiguqula ibe amakhilogramu (kg); noma siyazi ibanga eliphakathi kwezindawo ezimbili ngamakhilomitha (km) futhi sifuna ukuyiguqula ibe amamitha (m). Lokhu kuguqulwa kwamayunithi kungenziwa kusetshenziswa izinto zokuguqula noma kusetshenziswa ileli lokuguqula.

Isibonelo sezinkinga
Funda ingxoxo elandelayo ngokuguqulwa kwamayunithi bese ukwenze. imibuzo mayelana nokuguqulwa kwamayunithi phakathi kwamayunithi aphesheya
Inani eliyinhloko
Amayunithi obude
1. 10 km = ….. amamitha? (10)(1000) = Imitha ye-10.000
2. 10 km = ….. cm? (10)(100.000) = 1000.000 cm
3. 10 km = ….. mm? (10)(1000.000) = 10.000.000 mm
4. Amamitha ayi-10 = …… km? 10 / 1000 = 1 / 100 = 0,01 km
5. 10 cm = ….. km? 10 / 100.000 = 1 / 10.000 = 0,0001 km
6. 10 mm = ….. km? 10 / 1000.000 = 1 / 100.000 = 0,00001 km
7. Amamitha ayi-10 = ….. cm? (10)(100) = 1000 cm
8. Amamitha ayi-10 = ….. mm? (10)(1000) = 10.000 mm
9. 10 cm = ….. mm? (10)(10) = 100 mm
10. 10 cm = ….. amamitha? 10 / 100 = 1 / 10 = Imitha ye-0,1
11. 10 mm = ….. amamitha? 10 / 1000 = 1 / 100 = Imitha ye-0,01
12. 10 mm = ….. cm? 10 / 10 = Imitha ye-1
Iyunithi yesisindo
1. 10 kg = ….. amagremu? (10)(1000) = I-gram ye-10.000
2. 10 kg = ….. mg? (10)(1000.000) = I-10.000.000 mg
3. Amagremu ayi-10 = ….. mg? (10)(1000) = I-10.000 mg
4. Amagremu ayi-10 = …… kg? 10 / 1000 = 1 / 100 = 0,01 kg
5. 10 mg = ….. kg? 10 / 1000.000 = 1 / 100.000 = 0,00001 kg
6. 10 mg = ….. amagremu? 10 / 1000 = 1 / 100 = I-gram ye-0,01
Iyunithi yesikhathi
1. Amahora ama-2 = …. imizuzu? (2)(60) = imizuzu eyi-120
2. Amahora ama-2 = …. imizuzwana? (2)(3600) = imizuzwana engama-7200
3. Imizuzu emi-2 = …. imizuzwana? (2)(60) = imizuzwana eyi-120
4. Imizuzwana emi-2 = …. ama-millisecond? (2)(1000) = ama-millisecond angu-2000
Amayunithi okulinganisa atholiwe
1. 2 kPa (kilo Pascal) = ….. Pascal? (2)(1000) = 1000 Pascals
2. 2 kW (kilo Watt) = …… Amawathi? (2)(1000) = 1000 Amawathi
3. 2 MV (i-mega Volt) = …… Ama-volts? (2)(1000.000) = 1000.000 Ama-volts
4. 2 GHz (i-giga hertz) = …… i-Hertz? (2)(1000.000.000) = 2.000.000.000 i-Hertz
5. 2 km/ihora = ….. m/s? (2)(1000 m) / 3600 s = 0,5 m/s
6. 2 m/s = …… km/hora ? (2)(0,001 km) / 0.000 Amahora angu-27 = 7,4 km/hora
