Neither. 1m is really short while 25 dm is absurdly tall.
There are people with those heights but they are exceptions.
dm and dm refer to the same unit, decimetres. Therefore, 25 dm is equal to 25 dm (decimetres). Another, similar unit, the decametre, is abbreviated dam.
2.5 dm
25 dm
The length of a tissue box is most likely 25 cm. 25 m, or meters, would be far to large. One meter is about the length of a yard. 25 dm, ordecimeter's would also be wrong. There are ten decimeters in one meter. Therefore, 25 decimeters would be longer than 2.5 meters, which is much longer than a tissue box.
The height of a human is usually measured in cm.

I don't have a Yamaha 25 dm!

25 dm
The volume of the box in cubic centimeters is 5000 cm³ (25 cm * 2 dm * 1 dm * 10 cm/dm). The volume of the box in cubic decimeters is 10 dm³ (0.25 dm * 0.2 dm * 0.1 dm * 1000 cm³/dm³).
The length of a tissue box is most likely 25 cm. 25 m, or meters, would be far to large. One meter is about the length of a yard. 25 dm, ordecimeter's would also be wrong. There are ten decimeters in one meter. Therefore, 25 decimeters would be longer than 2.5 meters, which is much longer than a tissue box.
To convert 25 cm to decimeters, we note that 1 dm equals 10 cm. Thus, 25 cm is equal to 2.5 dm. Now, to express the ratio of 25 cm to 9 dm, we have 2.5 dm to 9 dm, which simplifies to 2.5:9. This can be further simplified by multiplying both sides by 2 to get a ratio of 5:18.
The centi- prefix means one hundredth → 1 cm = 0.01 cm The deci- prefix means one tenth → 1 dm = 0.1 cm → 25 cm : 9 dm = 25 × 0.01 m : 9 × 0.1 m = 0.25 m : 0.9 m = 0.25 : 0.9 = 25 : 90 The radio of 25cm to 9 dm is 25:90
since 1 dm is 10 cm, there are 25 cm in 2.5 dm.
The height of a human is usually measured in cm.
