100 weeks is just under two years — 1.9 years, or about 1 year and 11 months. It's the kind of span people round to "a couple of years": a toddler's first stretch of life, a typical master's degree, the time most New Year's resolutions are quietly abandoned and replaced. Small enough that you could almost count the weekends.
The straight answer
100 weeks ÷ 52 = 1.9 years. Counting the extra leap days (52.18 weeks per year), the more precise figure is 1.9 years — about 1 year and 11 months. For most purposes the round 1.9 years is the number you want.
What 100 weeks looks like

| 100 | 1.9 | ← this page |

A span you can actually count
The reason it's worth converting 100 weeks into years is that the two numbers feel completely different. "1.9 years" sounds like a vague block of time. "100 weeks" sounds like something you could tick off on a wall, because you almost could.
At one weekend per week, 100 weeks is also about 100 weekends — the unit a short span is really lived in. Whether that feels like a lot or a little depends mostly on what you're measuring against.
