How do you round 113.47 to the nearest meter?

Without knowing the units of 113.47 I can't.

If the units are:

• mm: 113.47 mm = 113.47 × 0.001 m = 0.11347 m → 0 m to the nearest m
• cm: 113.47 cm = 113.47 × 0.01 m = 1.1347 m → 1 m to the nearest m
• m: 113.47 m → 113 m to the nearest m
• km: 113.47 km = 113.47 × 1,000 m = 113,470 m → 113,470 m to the nearest m
• in: 113.47 in = 113.47 × 0.0254 m = 2.882138 m → 3 m to the nearest m
• ft: 113.47 ft = 113.47 × 0.3048 m = 34.585656 m → 35 m to the nearest m
• yd: 113.47 yd = 113.47 × 0.9144 m = 103.756968 m → 104 m to the nearest m
• fathoms: 113.47 fathoms = 113.47 × 1.8288 m = 207.513936 m → 208 m to the nearest m
• chains: 113.47 chains = 113.47 × 20.1168 m = 2,282.653296 m → 2,283 m to the nearest m
• furlongs: 113.47 furlongs = 113.47 × 201.168 m = 22,836.53296 m → 22,837 m to the nearest m
• miles: 113.47 miles = 113.47 × 1,609.344 m = 182,612.26368 m → 182,612 m to the nearest m

In each case I have looked at the digit after the decimal point and if it was 5 or more rounded up, otherwise rounded down.
