There are 25.4 millimetres in one inch. Therefore, rounded to two decimal places, 250 millimetres is equal to 250/25.4 = 9.84 inches.
There are 12 inches in one foot. Therefore, 250 feet is equal to 250 x 12 = 3000 inches.
There are 1000 millimetres in one metre. Therefore, 250 millimetres is equal to 250/1000 = 0.25 metres.
There are 100 millimetres in one decimetre. Therefore, 250 millimetres is equal to 250/100 = 2.5 decimetres.
There are 10 millimetres in one centimetre. Therefore, 250 centimetres is equal to 250 x 10 = 2500 millimetres.
18 inches = 457 millimetres.
67 inches = 1701.8 millimetres
1 Metre = 1000 Millimetres, therefore 250 Metres = 250,000 Millimetres.
There are 304.8 millimetres in one foot. Therefore, rounded to three decimal places, 250 millimetres is equal to 250/304.8 = 0.820 feet.
There is 1,000 millimetres in one metre, so to work this out multiply 250 by 1,000. The answer to the question is there are 250,000 millimetres in 250 metres.
The answer will depend on 250 of what! Millimetres, metres, parsecs, inches? Since you have not provided that information, I cannot provide a sensible answer.
One kilometre is equal to 1000 x 1000 = 1000000 millimetres. Therefore, 250 millimetres is equal to 250/1000000 = 0.00025 kilometres.
To convert from inches to millimetres, multiply by 25.4. In this instance, 0.051 x 25.4 = 1.2954 millimetres.
