As here in the US, we use Imperial units, yards, not meters. When using a target for 25M to sight in, what changes to look for? |

Nothing. Put your target at 25m and shoot. Laser if not already established points. All 16/M4 series are in meters and “most” sights/optics are too. Read about your specific example to be sure it is in meters rather than yards. I use whatever value the optic calls for or the rifle calls for….ex M1 Garands are in yards, M14s are in meters. |

Zeroing exactly 25 yards and never adjusting it will let you have a nearly 300 yards zero regardless of meters or yards for the sight since you’re never adjusting it. Now if there are any adjustments you make it could be off by a significant amount depending. I used to recommend strelok which lets you enter your optics and all that and you can have a pretty good idea of how to zero at 25 yards even if your optic is calibrated for meters. I have used it with some success. |

How much you are exposed to it heavily depends on your environment, in terms of people and location. Most advanced or theoretical science branches use almost exclusively metric units. The most common exposure I can think of is speedometers; most US cars include both metric and imperial units on the speedometer so the vehicles, without modification, can legally be sold and registered in Canada, too. If you've driven a car and checked your speed, you have seen evidence that in the US there is regular usage of both measurement systems. |

It kind of depends what sighting system you are using too.... if you have some graduated irons, I would stick to the units they are made for. Same for a BDC reticle. If you have a scope with a mil reticle, you can do whatever you want as long as the units you stick to are consistent. At ranges past about 300 or a little more, it really starts to matter; if you range something at 500yd and plug 500 into a calculator set to meters, you are going to miss unless it's a really big target. |
