| Details | The unit lm/Em² (lumen per square exametre) is a rarely used unit for measuring illuminance or the amount of light falling on a surface. Illuminance is a critical parameter in various fields like photography, architecture, and lighting design, as it quantifies how well an area is lit. The more commonly used unit for illuminance is lux (lx), which is equivalent to lumens per square meter (lm/m²). However, lm/Em² represents lumens per square exametre (1 Em² = 10¹⁸ m²), which is an incredibly large area (10¹⁸ times larger than a square meter). Using lm/Em² for everyday applications would result in very small numbers because an exametre is an enormous unit of length. Therefore, it isn't practical to use this unit for most situations. Instead, it would be more useful in unique scenarios that involve incredibly large distances or areas, such as astronomical measurements or large-scale scientific simulations. |
