Why You Need a Measurement Converter for Japan (日本の単位変換)
Japan uses the metric system exclusively for official measurements,
which can be a challenge for visitors and residents from countries
that use imperial units. Japanese government forms (住民票, visa
applications, driver's licence), medical forms, and school records
all require height in centimetres and weight in
kilograms. If your passport or home country documents
record your height in feet and inches or your weight in pounds or
stone, you will need to convert before filling out these forms.
For shopping, Japanese clothing sizes use a different numbering system
from US or European sizes. Women's tops use odd numbers (9, 11, 13)
rather than XS/S/M/L, and Japanese sizing generally runs one to two
sizes smaller than US equivalents. Japanese shoe sizes are simply the
foot length in centimetres (e.g. 25.0 = 25 cm foot), making them
straightforward to convert from US or EU sizes.
Height and Weight for Japanese Medical Forms (健康診断)
Annual health checks (健康診断, kenko shindan) are required for most
employees in Japan. These forms ask for height (身長, shinchou) in cm
and weight (体重, taijuu) in kg. Normal adult body temperature in Japan
is considered 36–37°C (96.8–98.6°F), and temperatures are always
recorded in Celsius on Japanese medical forms.
All conversions are approximate and based on standard conversion factors.
For medical or legal purposes, always verify your measurements directly.

holiday checker.
Frequently Asked Questions
-
What units does Japan use for height and weight?
Japan uses the metric system for all official measurements. Height
is recorded in centimetres (cm) on Japanese government forms, medical
records, and official documents. Weight is recorded in kilograms (kg).
If you are used to feet and inches for height or pounds and stone for
weight, use this converter to find your measurements in the Japanese
format before filling out forms.
-
How do Japanese clothing sizes compare to US sizes?
Japanese women's clothing sizes use odd numbers: size 7 (US XS/S),
size 9 (US S), size 11 (US M), size 13 (US L), size 15 (US L/XL).
Japanese men's clothing uses letter sizes (S, M, L, LL, 3L) similar
to US sizing but often runs smaller. Japanese sizes generally run
one to two sizes smaller than US or European equivalents. Always
check the specific brand's size chart as sizes vary.
-
How do Japanese shoe sizes work?
Japanese shoe sizes are measured in centimetres and represent the
length of the foot. For example, a Japanese size 25.0 means the foot
is 25 cm long, which corresponds to a US women's size 8 or men's
size 7. To convert, measure your foot in centimetres or use this converter.
-
What is the Japanese ring size system?
Japanese ring sizes use a numerical scale based on the inner
circumference of the ring in millimetres. Japanese size 1 corresponds
approximately to US size 1 and a diameter of 13.0 mm. Japanese ring
sizes go up in increments of about 0.8 mm diameter per size. To find
your Japanese ring size, measure the inner circumference of a ring
that fits well, or use the converter above.
-
How do I convert my height for a Japanese form?
To convert your height for a Japanese government or medical form,
use the height converter above. Enter your height in feet and inches
(e.g. 5 feet 7 inches) and the converter will calculate your height
in centimetres (e.g. 170 cm). Japanese forms typically require height
in whole centimetres rounded to the nearest cm. For weight, enter your
weight in pounds or stones and the converter will show your weight in
kilograms.
