The core reason for converting between these two units is simple: we need to translate between these different systems to understand and compare measurements. Think of it like translating between two different languages to communicate the same idea.
It can be frustrating, though. Imagine you’re following a recipe from a European cookbook, and it calls for 2 kg of flour. If you’re in the US, you might find yourself scratching your head, trying to figure out how much that is in pounds.

Wesley Wanggira has opinions about expert business advice. Informed ones, backed by real experience — but opinions nonetheless, and they doesn't try to disguise them as neutral observation. They thinks a lot of what gets written about Expert Business Advice, Market Analysis and Reports, Financial Planning Tips is either too cautious to be useful or too confident to be credible, and they's work tends to sit deliberately in the space between those two failure modes.
Reading Wesley's pieces, you get the sense of someone who has thought about this stuff seriously and arrived at actual conclusions — not just collected a range of perspectives and declined to pick one. That can be uncomfortable when they lands on something you disagree with. It's also why the writing is worth engaging with. Wesley isn't interested in telling people what they want to hear. They is interested in telling them what they actually thinks, with enough reasoning behind it that you can push back if you want to. That kind of intellectual honesty is rarer than it should be.
What Wesley is best at is the moment when a familiar topic reveals something unexpected — when the conventional wisdom turns out to be slightly off, or when a small shift in framing changes everything. They finds those moments consistently, which is why they's work tends to generate real discussion rather than just passive agreement.
