周波数 Converter
無料周波数換算ツール, Hz、kHz、MHz、GHz、THz、RPMを瞬時に換算
OmniConverterの無料オンライン周波数換算ツールで、Hz、kHz、MHz、GHz、THz、RPMの間を即座に換算。1キロヘルツは1,000ヘルツ、1メガヘルツは1,000kHz、1ギガヘルツは1,000MHzです。電子機器、オーディオエンジニアリング、CPU速度などに正確な即座の結果を提供します。
使い方
簡単な3ステップで変換できます。
周波数の値を入力
「入力値」欄に周波数測定値を入力します。例えば 2400 で 2400 MHz（Wi-Fiの典型値）、60 で 60 Hz（交流電源周波数）を変換できます。
変換元と変換先の周波数単位を選択
左で入力単位（例: ヘルツ、キロヘルツ、メガヘルツ、ギガヘルツ、RPM）、右のドロップダウンで出力単位を選びます。
変換後の周波数結果を確認
変換結果が即座に表示されます。電子工学、オーディオエンジニアリング、無線通信、CPUクロック比較、モーターのRPMからHzへの計算に役立ちます。

実用的なユースケース
日本の商用電源は地域によって50Hz（東日本：東京電力、東北電力）と60Hz（西日本：関西電力、中国電力）に分かれています。富士川を境にしたこの50/60Hz境界は世界でも珍しく、家電製品の購入時に対応周波数の確認が必要です。FMラジオは76〜95MHz（NHK-FM、TOKYO FM、J-WAVEなど）で、世界的な87.5-108MHzとは異なる独自バンドです。CPUのクロック周波数はGHz単位（Intel Core i9-14900Kは最大6.0GHz）。ディスプレイのリフレッシュレートはゲーマー向けに144Hz/240Hz/360Hzが一般化。Wi-Fiは2.4GHz帯と5GHz帯のデュアルバンドが標準。5Gでは3.7GHz帯や4.5GHz帯、28GHz帯（ミリ波）も使われます。オーディオのサンプリングレート：CDは44.1kHz、ハイレゾは96kHzや192kHz。USP（超音波検査）は2-15MHz。電気自動車のモーター回転数は10,000-20,000 RPM。電子レンジは2.45GHz。心拍数はbpm（60bpm=1Hz）。PWM制御のLED調光は数百Hz〜数kHz。放送衛星（BS）の周波数は11.7-12.2GHz。パルスレーザーの繰り返し周波数はkHzからMHz。新幹線の架線周波数は60Hz。

よくある換算の質問への回答
日本は50Hz/60Hzどっち？+
東日本は50Hz、西日本は60Hz。静岡県の富士川が境界です。変換器は両方に対応しています。
FMラジオの周波数は？+
日本ではFM 76-95 MHz、AM 531-1,602 kHzが放送に使われています。
HzをkHzに換算するには？+
Hzを1,000で割ります。
MHzをGHzに換算するには？+
MHzを1,000で割ります。
5Gの周波数帯は？+
日本の5Gはsub6（3.7-4.5 GHz）とミリ波（28 GHz）を使用。
RPMをHzに換算するには？+
RPMを60で割ります。1,800 RPM = 30 Hz。
電源周波数50Hzと60Hzの違いは？+
周波数が違うとモーターの回転数が変わります。50Hz地域の製品を60Hz地域で使うと高速回転します。
