Because the inch is defined as exactly 2.54 cm, these values carry no rounding error. Handy anchors: a foot is 30.48 cm, a yard is 91.44 cm, and 6 feet is 182.88 cm. Screen sizes are the common exception to watch — a "24 inch" monitor is 24 inches diagonally, not wide, so its actual width is closer to 53 cm.
