KOMPAS.com - Pengurukuran atau konversi waktu adalah skala waktu yang memudahkan manusia untuk menentukan lama berlangsungnya suatu kejadian.
Dalam penghitungan waktu, kita lazim mengenal tahun, bulan, hari, hingga detik. Dalam kehidupan ini, manusia diberikan waktu satu hari, 24 jam, 60 menit, dan 3.600 detik.
Selain itu, satuan waktu juga dapat bonversikan nilainya ke satuan waktu lainnya. Berikut rangkuman satuan waktu dalam hari, minggu, bulan, dan tahun:

Satuan waktu dalam hari
Dilansir dari Buku Pembelajaran Matematika SD Kelas Tinggi (2022) oleh Nurlev Avana dan teman-teman, ini penjelasan terkait satuan waktu dalam hari:
- 1 minggu = 7 hari
- 1 bulan (rata-rata)= 30,41 hari
- 1 bulan = 28, 29, 30, 31 hari
- 1 tahun = 365 hari
- 1 tahun (kabisat) = 366 hari (29 Februari)
Satuan waktu dalam minggu
Berikut satuan waktu dalam minggu:

`; document.querySelector('.kompasidRec').innerHTML = htmlString; } else { document.querySelector(".kompasidRec").remove(); } } else { document.querySelector(".kompasidRec").remove(); } }});xhr.open("GET", endpoint);xhr.send();
- 1 bulan = 4,34 minggu
- 1 tahun = 52,14 minggu

Satuan waktu dalam bulan
Berikut satuan waktu dalam bulan:
- 1 triwulan = 3 bulan
- 1 caturwulan = 4 bulan
- 1 semester = 6 bulan
- 1 tahun = 12 bulan
- 1 lustrum = 60 bulan = 5 tahun
- 1 windu = 96 bulan = 8 tahun
- 1 dekade = 120 bulan = 10 tahun
Satuan waktu dalam tahun
Berikut satuan waktu dalam tahun:
- 1 lustrum = 5 tahun
- 1 windu = 8 tahun
- 1 dekade = 10 tahun (1 dasawarsa)
- 1 abad = 100 tahun (10 dasawarsa)
- 1 masehi = 1.000 tahun (1 milenium)

Jumlah hari dalam bulan (Januari-Desember)
Berikut rincian banyaknya hari dalam bulan Januari sampai Desember:
- Januari = 31 hari
- Februari = 28/29 hari
- Maret = 31 hari
- April = 30 hari
- Mei = 31 hari
- Juni = 30 hari
- Juli = 31 hari
- Agustus = 31 hari
- September = 30 hari
- Oktober = 31 hari
- November = 30 hari
- Desember = 31 hari
Pada tahun kabisat ada 366 hari, yang terjadi setiap 4 tahun dan kelipatan 4. Misalnya, tahun 2004, 2008, 2012, 2016, 2020, dan seterusnya.
Tanda dari tahun kabisat adalah adanya penambahan 1 hari pada bulan Februari, yakni 29 Februari.
Berikut beberapa soal dan jawaban terkait konversi waktu.

Contoh soal 1
4 windu + 312 minggu - 9 tahun = ... tahun
Jawab:
Pertama, kita samakan terlebih dulu satuannya menjadi tahun.
4 windu = 4 x 8 tahun = 32 tahun
312 minggu = 312 : 52 = 6 tahun
Maka, 4 windu + 312 minggu - 9 tahun = 32 + 6 - 9 = 29 tahun
