Untuk soal yang sedikit lebih rumit biasanya ditampilkan rumusnya, tinggal otak-atik, pindah kanan kiri, atas bawah, masukkan satuannya baru dikonvert ke dimensi. Sekedar Contoh: Diberikan formula gaya gravitasi antara dua benda sebagai berikut dengan F adalah gaya (Newton) m 1 dan m 2 adalah massa kedua buah benda (kg), r adalah jarak kedua benda (m) dan G adalah suatu konstanta yang akan dicari dimensinya. Dari rumus diatas setelah dibolak-balik didapatkan bahwa masukkan satuannya bawa ke kg, m dan s. Untuk satuan gaya lihat daftar diatas, didapat Contoh berikutnya: Diberikan persamaan gaya pegas F = k Δ X Dimana F adalah gaya pegas (Newton), Δ X adalah pertambahan panjang pegas (meter)

8 dan k adalah konstanta pegas. Dimensi konstanta pegas?
