Units explained
Square Dekameter
A square dekameter is a metric unit of area equal to 100 m². It is identical in value to the are.
Derived by squaring the dekameter (10 m). The deca- prefix comes from the Greek 'deka' (ten).
Square dekameters are functionally equivalent to ares. In contexts where the prefix system is preferred, dam² may be used in place of 'are' for clarity.
Dekameter has been part of the metric system since 1795.
Square Yoctometer
A square yoctometer is a metric unit of area equal to one square yoctometer (10⁻²⁴ m × 10⁻²⁴ m = 10⁻⁴⁸ m²). It is the smallest SI prefix-derived area unit defined and exists primarily for theoretical completeness.
Derived by squaring the yoctometer (10⁻²⁴ m), which uses the SI prefix yocto- adopted by the CGPM in 1991. The yocto- prefix originates from the Latin 'octo' (eight), referring to the 10⁸ thousand-grouping in the power-of-thousand scheme.
Square yoctometers have no current practical application. The yoctometer scale itself lies far below any physically measurable length, including the Planck length. The unit is included for SI catalogue completeness.
SI prefix yocto- adopted in 1991; square area defined by mathematical squaring.
Square Dekameter to Square Yoctometer conversion formula
The relationship between square dekameters and square yoctometers:
To convert square dekameters to square yoctometers, multiply the value in square dekameters by 1e+50. To reverse, multiply square yoctometers by 1e-50.

Step-by-step: convert square dekameters to square yoctometers
- Write down the value in square dekameters (dam²).
- Multiply that value by the factor 1e+50.
- The product is the equivalent value in square yoctometers (ym²).
- To reverse, multiply the square yoctometer value by 1e-50.
Worked examples
Example 1 — Convert 1 dam² to ym²:
1 × 1e+50 = 1e+50 ym²
Example 2 — Convert 100 dam² to ym²:
100 × 1e+50 = 1e+52 ym²
