1990
The Yamaha 25 DM model was produced in the early 1980s, specifically around 1981 to 1983. The serial number you provided, 695 s 01543, indicates that it is likely from that production period. To confirm the exact year, it's best to consult Yamaha's production records or a dedicated vintage Yamaha forum for more precise identification based on the serial number.
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
Neither. 1m is really short while 25 dm is absurdly tall. There are people with those heights but they are exceptions.
I don't have a Yamaha 25 dm!

2.5 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 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.

They are equivalent.
2.5 meters is 25 decimeters.
1 dm = 10 cm so 7.5 dm/90 cm = 75 cm / 9 cm = 75/9 = 25/3
