Semester to Quarter Credits Calculator

Multiply your semester credits by 1.5. For example, 16 semester credits equal 24 quarter credits (16 x 1.5), and 30 semester credits equal 45 quarter credits. The 1.5 factor reflects that a full-time academic year holds about 30 semester credits or 45 quarter credits.

Divide your quarter credits by 1.5, which is the same as multiplying by two-thirds (about 0.667). For example, 45 quarter credits equal 30 semester credits (45 / 1.5) and 12 quarter credits equal 8 semester credits. Schools usually round the converted total to two decimals.

Semester schools run two main terms a year and quarter schools run three, so the same academic year holds roughly 30 semester credits or 45 quarter credits. Dividing 45 by 30 gives 1.5, so one semester credit equals 1.5 quarter credits. This 3 to 2 ratio is the standard most US registrars publish for transfer credit.

The 1.5 factor is the standard arithmetic conversion, but each school applies its own transfer rules. Some round each course to the nearest half credit, cap the total transferable credits, or require a minimum grade. Use this calculator to estimate the count, then confirm the official total with the receiving school's registrar or transfer office.

A typical US bachelor's degree is about 120 semester credits or 180 quarter credits, which is roughly four years of full-time study at 30 semester (45 quarter) credits per year. Convert your transcript total and compare it to the degree requirement in the target system to gauge your progress.
