Conversion Formula Between cm and shaku

In kimono sewing, we use a unit called ” Kujira-shaku “.
Here is the formula for converting cm to Kujira-shaku.


Conversion formula between cm and shaku


For example, when converting a height of 165 cm to a scale
165 x 2.64 = 435 (rounding down this time to the nearest whole number)

This is read as “4-shaku 3-sun 5-bu.”

The one place is bu(分)
The ten place is sun(寸)
The hundred place is shaku(尺)

Why are the numbers that multiply the conversion formula different?

“尺 = cm x 2.64” is equal to “cm = 尺 ÷ 2.62.”
In other words, “cm = 尺 x (1 ÷ 2.64).”

(1 ÷ 2.64) is calculated first.
1 ÷ 2.64 = 0.378787878 = 0.3788

In other words, cm = 尺 x 0.3788

You can see that 尺 → cm and cm → 尺 are the same calculation.
