Half Calculator
Halving sounds trivial until the number is 3/4 cup of cocoa and you are making a half batch. This calculator halves anything: whole numbers, decimals, fractions (3/4), and mixed amounts (2-1/2) — giving the exact fractional answer (3/8) alongside the decimal, so the reduced recipe stays correct.
It is the quiet hero of batch cooking, scaling down for two, dividing bills between two people, and every math worksheet with the word 'half' in it.
How to use
- Type any amount — whole number, decimal, fraction like 3/4, or mixed like 2-1/2.
- Read the exact half as a fraction and as a decimal.
- Halve several ingredients in a row while scaling a recipe down.
Frequently asked questions
What is half of 3/4?
3/8. Dividing a fraction by 2 doubles its bottom number: 3/4 becomes 3/8. In cups, 3/8 cup is 6 tablespoons — a common half-batch conversion.
What is half of 2/3?
2/3 halved is 1/3 (double the bottom number: 2/3 → 2/6 = 1/3). This trips people up because the decimal form, 0.333, looks nothing like 0.666 halved — but it is exactly half.
What is half of 1 and 3/4 cups?
7/8 cup. Convert 1-3/4 to 7/4 first, halve it to 7/8 — just under a full cup. Practically: a scant cup.
How do I halve an odd number?
Odd whole numbers halve to .5 — half of 7 is 3.5. For fractions with odd denominators (like 1/2), double the denominator instead: half of 1/2 is 1/4.
