Prefiks Metrik atau SI (Le Système International d'Unités) adalah berdasarkan kekuatan sepuluh. Mereka adalah pengubah pada kata dasar yang memberitahu kita unit pengukuran. Untuk mengkonversi satu unit metrik ke unit metrik yang lain dengan tepat, anda perlu menentukan yang mana antara dua prefiks mewakili jumlah yang lebih besar dan kemudian tentukan "jarak" eksponensial di antara mereka.
