The conversion of 0.12 repeat to grams results in approximately 1.2 grams.
Since “0.12 repeat” indicates a repeating decimal of 0.121212…, and assuming it represents a measurement in units where “repeat” signifies the recurring part, the conversion involves recognizing that 0.12 repeat equals 0.12̅, which is 0.12 with an infinite sequence of 12. To convert this to grams, we interpret the value directly as a decimal for measurement purposes, assuming the units are grams, so 0.12 repeat is approximately 1.2 grams when multiplied by 10.
Conversion Formula
The conversion from repeat decimal to grams depends on interpreting the repeating decimal as a fraction. For 0.12̅, the formula is: (number of repeating digits) / (9 * 10^(number of non-repeating digits)). Here, 0.12̅ is a repeating decimal with 2 digits. So, 0.12̅ equals (12 / 99), which simplifies to (4 / 33). When multiplied by the measurement unit, this yields the gram equivalent. For example, 0.12̅ as a decimal is 12 divided by 99, approximately 0.121212…, which when scaled by 10 gives roughly 1.2 g.
Conversion Example
- Convert 0.25 repeat to grams:
- Express as fraction: 0.25̅ = 25 / 99.
- Simplify if needed, but 25 / 99 is already in lowest terms.
- Multiply by measurement units (assuming units are grams): result is approximately 25 / 99 g ≈ 0.2525 g.
- Convert 0.33 repeat:
- Express as fraction: 0.33̅ = 33 / 99.
- Simplify: 33 / 99 = 1 / 3.
- Result: 1 / 3 g ≈ 0.3333 g.
- Convert 0.1 repeat:
- Express as fraction: 0.1̅ = 1 / 9.
- Result: 1 / 9 g ≈ 0.1111 g.

Conversion Definitions
“Repeat” refers to a decimal number where a sequence of digits repeats endlessly, such as 0.121212…, representing a recurring pattern in the decimal expansion. “g” stands for grams, a basic unit of mass measurement in the metric system, used to quantify weight or mass of objects.
Conversion FAQs
How do I convert a repeating decimal to grams?
To convert a repeating decimal to grams, first express the decimal as a fraction, then multiply by the measurement unit (assumed to be grams). For example, 0.12̅ equals 12/99, which when multiplied by the unit gives the weight in grams.
Why is 0.12 repeat represented as 12/99?
Because repeating decimals can be written as fractions where numerator and denominator are related to the length of the repeating pattern. For 0.12̅, the 2-digit pattern repeats, so it equals 12 divided by 99, the number formed by nine’s for the digits.
Can I convert other repeating decimals to grams using this method?
Yes, this method works for any repeating decimal. Just write the decimal as a fraction, simplify if possible, then multiply by the measurement unit. This approach is valid for converting repeat decimals to grams or other units.
What if my repeat decimal has non-repeating parts?
When non-repeating parts are present, the conversion involves combining the non-repeating and repeating parts into a single fraction, then performing the multiplication to get grams. The process is more complex but follows similar principles.
