キロワット時をキロジュールに換算する

以下の解説はキロワット時をキロジュールに換算する (kwh → kj) のままです。エネルギー

キロワット時をキロジュールに換算する方法

キロワット時の値に 3600 を掛けます。キロワット時は電力量計の単位、キロジュールは物理と食品表示の単位であり、同じエネルギーを電力会社と実験室がそれぞれの言葉で数えているだけです。

kJ = kWh × 3600逆方向は 3600 で割ります。

この二つの単位が使われる場所

キロジュールは欧州の食品表示で義務づけられており、キロカロリーはその横に併記できるだけで、代わりに置くことはできません。

1 時間は 3600 秒、1 ワットは毎秒 1 ジュールですから、キロワット時は定義上 3,6 メガジュールとなり、測定値ではなく厳密値です。キロワット時は国際単位系の単位ではありませんが、時間は国際単位系と併用が認められています。算出方法と出典.

よくある質問

kWh と kW/h、正しいのはどちらですか。

kWh、または中黒を用いた kW·h が正しい書き方です。斜線は除算を表すため、kW/h は毎時何キロワット、つまり電力が増える速さを意味してしまい、エネルギーの量とは無関係になります。キロワット時は逆に積であり、電力に時間を掛けたものです。2 kW の暖房器具を 90 分使えば 3 kWh、すなわち 10,800 kJ です。国際単位系なら同じエネルギーを 3,6 メガジュールと書きます。時間はその時間単位ではないからです。

電気ケトルには何キロジュール必要ですか。

1.5 リットルの水を 15 度から 100 度にするには 534 キロジュール、つまり 0.148 キロワット時が必要です。計算は一行です。水 1 キログラムを 1 度上げるのに 4.186 キロジュールが要り、上げる幅は 85 度あります。2200 ワットのケトルなら 4 分あまり、実際は容器と周囲の空気が分を取るため 1 割ほど長くかかります。

ガス料金はなぜ立方メートルをキロワット時に換算するのですか。

メーターは体積を測るのに、ガスはエネルギーとして売られるからです。事業者は検針した立方メートルに換算係数を掛けます。係数は供給されたガスの組成と土地の標高によって変わり、フランスでは 1 立方メートルあたりおよそ 10.6 から 12.8 キロワット時、つまり 38,000 から 46,000 キロジュールです。天然ガス 1 立方メートルは電気 1 キロワット時の 10 倍ほどのエネルギーを運ぶわけで、二つの請求書をキロワット時の単価だけで比べられない理由もここにあります。

TNT 1 キログラムは何キロジュールですか。

ちょうど 4184 キロジュール、すなわち 1.162 キロワット時です。TNT 換算トンが熱化学カロリー 10 億分と定めた約束の単位だからで、TNT 1 グラムはきっかり 1 キロカロリーにあたります。爆発を測る単位は食品表示の単位そのものだということです。約束は丸くても物質はそうではなく、トリニトロトルエンが実際に出すのは 1 キログラムあたり 4600 キロジュール近くです。2200 ワットのケトルは同じエネルギーに 32 分で達します。

100 キロワット時をガソリンで持つか電池で持つか、何が違いますか。

片方は 11 リットル、もう片方は半トン超です。ガソリン 1 リットルはおよそ 32 メガジュール、つまり 8.9 キロワット時を運ぶので、100 キロワット時は 11 リットル、12 キログラムに収まります。同じエネルギーをリチウム電池に入れると 500 から 600 キログラムの塊が要ります。電池は 1 キログラムあたり 0.18 キロワット時ほどで頭打ちですが、ガソリンは 12.2 あるからです。質量比は 70 に近いものの、実用上の差はずっと小さく、内燃機関がタンクのエネルギーを動きに変えるのは 4 分の 1 程度、電動系は 9 割近くに達します。
