Mo tēnei tātaitai

An electricity cost calculator turns an appliance’s wattage into money by tracing the chain from power to energy to price. Energy in kilowatt-hours is power in kilowatts times hours of use, so a device’s daily energy is its watts ÷ 1,000, multiplied by the hours it runs each day; the cost is that energy times your price per kWh. Advanced fields let you set the number of identical units and how many days a week they run, so occasional loads are averaged fairly across the calendar.

As a worked example, a 100 W device left on 5 hours a day uses 0.1 kW × 5 = 0.5 kWh daily. At $0.15 per kWh that is about $0.075 a day, which works out to roughly $2.28 a month and $27.40 a year (the tool uses 30.44 days per month and 365.25 days per year for accuracy). A 1,500 W space heater run the same 5 hours costs fifteen times as much — around $1.13 a day — which quickly shows why high-wattage heating dominates a power bill.

The calculator returns the daily, monthly and yearly cost plus the annual energy in kWh, and a period-by-period schedule you can open to compare day, week, month and year. It is the practical way to decide whether an old fridge is worth replacing, budget for a new appliance, spot the phantom cost of always-on devices, or compare the running cost of two products with different wattages.

Ko nga pātai e pā ana

He pēhea te tatau i te utu o te mahi o te pūrere?

Ko te pūngao o ia rā i roto i te kWh ko te hiko i roto i ngā kilowati (watts ÷ 1000) ngā wā e haere ana i ia rā. Whakarea e tōna utu i ia kWh mō te utu o ia rā, kātahi e 30, 365 rānei mō ngā tau o te marama me te tau.

He nui te utu o te pūrere 100 W hei whakahaere?

I te 5 wā i ia rā ka whakamahia e ia 0.1 kW × 5 = 0.5 kWh i ia rā. I te $0.15 ia kWh e tata ana ki te $0.075 i ia rā, tata ki te $2.25 i ia marama, $27 rāneia tau.

E tatau ana te hiko tūpono?

He — he maha ngā pūrere e tango ana i ētahi watts ahakoa ka whakapā atu. Mēnā e hiahia ana koe ki te whakauru i te tūponotanga, ka tāpiri i tōna wattage i runga i ngā wā e noho ana i te tūponotanga, ka whakahaere rānei i tētahi tātaitanga motuhake mō te utu tūponotanga.

He pēhea te utu o a au i ētahi pūrere ōrite i tētahi wā?

Ka whakamahia te āpure hōhonu "tau o ngā wae". Te tekau ngā pūhihi 10 W e haere tahi ana, he ōrite te utu ki tētahi utu 100 W, nō reira ka whakarea te tātaitai te pūngao e te nui i mua i te hoatu i tōna utu i ia kWh.

He aha mēnā ka haere tonu te pūrere i ētahi rā o te wiki?

Ka whakaritea "ngā rā i whakamahia i ia wiki" i roto i ngā kōwhiringa tiketike. Ka whakawaengatia e te utauta te pūngao puta noa i te rārangi katoa — ka whakapūtātia tētahi pūrere e whakamahia ana i te 5 o te 7 rā hei 5/7 o te whakamahi ā-rohe — kia noho ai ngā tau o te marama me te tau.

I hea ka kitea e au te pūngao o te pūrere?

Ka tirohia te tohu whakarārangi, te papa inoa, te pukapuka rānei, i te nuinga o te wā ka hoatu ki roto i ngā watts, hei volts rānei me ngā amper (tāpiri i a rātau mō ngā watts). Mō tētahi tātaitai o te ao tūturu, ka ine te kaitirotiro pūngao plug-in i te tāruatanga tūturu, ka taea e koe te tāuru hāngai ki tēnei wāhi.

He aha te take kāore i te tika te utu o ahau o te marama me te tau, e 30 me te 365 ngā wā o te utu o ia rā?

Ka whakamahia e te tātaitai te maramataka ā-tau o te 30.44 rā me te tau o te 365.25 rā, kaua ko te 30 me te 365, nā reira ko te utu $0.075 i ia rā e tata ana ki te $2.28 i tētahi marama me te $27.40 i tētahi tau — he nui ake i te whakatau tata.
