How to Convert Centimeters to Picas
To convert centimeters to picas, multiply the length by the following conversion ratio: 2.3622047 picas/centimeter.
Since one centimeter is equal to 2.3622047 picas, you can use this simple formula to convert:
The length in picas is equal to the length in centimeters multiplied by 2.3622047.
For example, here's how to convert 5 centimeters to picas using the formula above.
How Many Picas Are in a Centimeter?
There are 2.3622047 picas in a centimeter, which is why we use this value in the formula above.
Our centimeter fraction and decimal calculator can convert centimeters and picas, and it automatically converts the results to US customary, imperial, and SI metric values.
Centimeters and picas are both units used to measure length. Keep reading to learn more about each unit.
How to Convert Centimeters to Fractional Inches (1/16″, 1/32″ & 1/64″)
Plain-language method for turning decimal inches into a standard tape-measure or machinist ruler fraction
Calculators give you a decimal number (such as 1.968504 in), but tape measures and woodworking rulers are marked in binary fractions of an inch—most commonly 1/16″ on carpenter tapes, 1/32″ on fine woodworking rules, and 1/64″ on machinist scales.
Here is the step-by-step worked example for converting 5 centimeters (cm) into fractional inches:
- Find the decimal inches result: Convert 5 cm to inches to get 1.968504 in.
- Separate the whole inches from the decimal part: Keep the whole number 1 aside, leaving the decimal remainder 0.968504.
- Multiply the decimal part by your desired fraction denominator (16, 32, or 64) and round half up: Multiply 0.968504 by 16, 32, or 64, then round to the nearest whole number (values ending in .5 round up).
- Reduce the fraction to lowest terms: If the rounded top number (numerator) is even, divide both top and bottom by 2 (or their Greatest Common Divisor) until the top number is odd, then combine with your whole inches.
What Is a Centimeter?
A centimeter is a metric unit of length equal to one-hundredth (1/100) of a meter, which is the International System of Units (SI) base unit of length. One centimeter is also equal to 10 millimeters or approximately 0.39370079 inches. [1]
The centimeter, or centimetre, is part of the SI metric system used worldwide for everyday, scientific, and clinical measurements. Centimeters can be abbreviated as cm; for example, 1 centimeter can be written as 1 cm.
In the metric system, "centi" is the Latin-derived prefix for hundredths, or 10⁻². Because 1 international inch is legally defined as 2.54 centimeters, converting between centimeters and inches is anchored by an exact mathematical constant.
Centimeters are measured using metric rulers, tailor's measuring tapes, stadiometers (for human height), and vernier calipers across carpentry, apparel sizing, school science, and medical charts.
What Is a Pica?
A pica is a unit of length equal to 0.0042333 meters (m), the base unit for length. Typographical unit equal to 12 points or 1/6 of an inch (4.2333 mm). [2]
The pica is classified as a standard unit of length. Picas can be abbreviated as pc; for example, 1 pica can be written as 1 pc.
When working with picas (pc) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.
In practice, picas (pc) are widely used across fine-tolerance laboratory, analytical, and micro-scale length measurements within international standard workflows, engineering documentation, and technical data sheets.
When converting length between centimeters (cm) and picas (pc), keep full floating-point precision (1 cm = 2.3622047 pc; 1 pc = 0.4233333 cm) during intermediate calculations and round only the final pica figure to match your instrument tolerance.
