Ngā pūnaha wae rerekē
Ka taea e tātou te whakarerekē, te mahi rānei te tahuritanga o ngā waeine i roto i tētahi pūnaha wae motuhake ki tētahi atu pūnaha wae, hei tauira mai i te Pūnaha Piritana ki roto Pūnaha Ao Whānui rānei te ritenga kē. Hei tauira, ki te ine tātou i te roa o tētahi tēpu mā te whakamahi i tētahi rūrū i roto i ngā inihi (te Pūnaha Piritana) ā, e hiahia ana tātou ki te whakaatu i te roa i roto i ngā mita (te Pūnaha Ao Whānui), ka taea e tātou te huri i te ine mai i ngā inihi ki ngā mita. Ka taea tēnei hurihanga mā te whakamahi i tētahi tauwehe hurihanga.
Pūnaha wae kotahi
Ka taea hoki e tātou te huri i ngā waeine i roto i te pūnaha waeine kotahi, pērā i te Pūnaha Waeine o te Ao. Hei tauira, e mōhio ana tātou ki te papatipu o tētahi mea i roto i te karamu (g) ā, e hiahia ana tātou ki te huri ki te kirokaramu (kg); e mōhio ana rānei tātou ki te tawhiti i waenganui i ngā wāhi e rua i roto i te kiromita (km) ā, e hiahia ana tātou ki te huri ki te mita (m). Ka taea te mahi i ēnei hurihanga waeine mā te whakamahi i ngā tauwehe hurihanga, mā te whakamahi rānei i tētahi arawhata hurihanga.
Arawhata tahuritanga waeine papatipu
Arawhata tahuritanga wae roa
Ngā tauwehenga tahuritanga wae SI mō te roa me te papatipu
Tauira raruraru
Akohia te kōrero e whai ake nei mō ngā tahuritanga waeine, kātahi ka mahi. ngā pātai mō te whakawhiti waeine i waenga i ngā waeine o te ao
Te moni matua
Ngā waeine roa
1. 10 kiromita = ….. mita? (10)(1000) = 10.000 mita
2. 10 km = ….. cm? (10)(100.000) = 1000.000 cm
3. 10 kiromita = ….. mm? (10)(1000.000) = 10.000.000 mm
4. 10 mita = …… km? 10 / 1000 = 1 / 100 = 0,01 km
5. 10 cm = ….. km? 10 / 100.000 = 1 / 10.000 = 0,0001 km
6. 10 mm = ….. kiromita? 10 / 1000.000 = 1 / 100.000 = 0,00001 km
7. 10 mita = ….. henimita? (10)(100) = 1000 cm
8. 10 mita = ….. mm? (10)(1000) = 10.000 mm
9. 10 henimita = ….. henimita? (10)(10) = 100 mm
10. 10 henimita = ….. mita? 10 / 100 = 1 / 10 = 0,1 mita
11. 10 mm = ….. mita? 10 / 1000 = 1 / 100 = 0,01 mita
12. 10 mm = ….. henimita? 10 / 10 = 1 mita
Te waeine o te papatipu
1. 10 kg = ….. karamu? (10)(1000) = Nama 10.000
2. 10 kg = ….. mg? (10)(1000.000) = 10.000.000 mg
3. 10 karamu = ….. mg? (10)(1000) = 10.000 mg
4. 10 karamu = …… kg? 10 / 1000 = 1 / 100 = 0,01 kg
5. 10 mg = ….. kg? 10 / 1000.000 = 1 / 100.000 = 0,00001 kg
6. 10 mg = ….. karamu? 10 / 1000 = 1 / 100 = Nama 0,01
Wāhanga o te wā
1. 2 hāora = …. meneti ? (2)(60) = 120 meneti
2. 2 hāora = …. hēkona ? (2)(3600) = 7200 hēkona
3. 2 meneti = …. hēkona ? (2)(60) = 120 hēkona
4. 2 hēkona = …. mirihekona? (2)(1000) = 2000 mirihekona
Ngā waeine ine i ahu mai
1. 2 kPa (kilo Pascal) = ….. Pascal? (2)(1000) = 1000 Pascal
2. 2 kW (kiro Wati) = …… Wati? (2)(1000) = 1000 Wati
3. 2 MV (mega Volt) = …… Ngā Volt? (2)(1000.000) = 1000.000 Ngā Volt
4. 2 GHz (giga hertz) = …… Hertz ? (2)(1000.000.000) = 2.000.000.000 Hertz
5. 2 kiromita/hāora = ….. m/h? (2)(1000 m) / 3600 h = 0,5 m/h
6. 2 m/s = …… km/haora ? (2)(0,001 km) / 0,00027 hāora = 7,4 km/haora
