概要+++++++++++++++++++++++++++++++ 天気予報などで、 「明日は風速20m/sの強風が吹くでしょう」と、 よく言われます。 しかし、風速20m/sと言われても、 どのくらいの風速なのか なかなかピンとこないものです。 また、大リーグの放送を見ていて、 ピッチャーが投げたボールの速度が 95mileと言われて、 時速でないと感動も一歩遅れてしまうもの。 そんな時、このアプリ「Convert」を お使いください。 よく使う単位の変換から、 あまりお目にかからない単位の変換まで、 このアプリにおまかせください。 操作方法++++++++++++++++++++++++++ アプリを起動するとすぐに、 各単位変換の選択画面が表示されます。 その中から目的の単位変換を選択してください。 各単位変換画面では、 1.変換元となる数値を入力し、 2.その数値の単位を選択し、 3.画面下部の変換ボタンをタップ してください。 なお、数値入力時には、数値以外が入力された場合、 再度正しい数値を入力するメッセージが表示されます。
